PAPER

My essay on "The Bibliographical Description of Paper" was pub-
lished in Studies in Bibliography, 24 (1971), 27–67, and reprinted in Readings
in Descriptive Bibliography
, ed. John Bush Jones (1974), pp. 71–115, and in
my Selected Studies in Bibliography (1979), pp. 203–243. I was pleased that
my approach was approved by the great scholar of paper, Allan Steven-
son, whom I had consulted shortly before the end of his life, when we were


38

both doing research at the Newberry Library. Since that time four schol-
ars have made the most significant advances in the study of paper from a
bibliographical point of view: David L. Vander Meulen, Paul Needham,
B. J. McMullin, and John Bidwell.

Of their publications, the one with the widest applicability to biblio-
graphical description, and a fundamental essay for the analysis of paper, is
Vander Meulen's "The Identification of Paper without Watermarks: The
Example of Pope's Dunciad," in Studies in Bibliography, 37 (1984), 58–81.
(Three years earlier he had discussed and illustrated the various tech-
niques taken up here in his pioneering 1981 dissertation, a descriptive
bibliography of Pope's Dunciad; see pp. 47–58 for his general account
and pp. 72–77 for one outstanding example.) Most previous bibliographi-
cal work on paper (including mine) had emphasized watermarks and the
chainline spaces close to them and had either stated or implied that all
the other chain spaces were equal to each other. But Vander Meulen
points out that the spaces between chains in handmade paper vary within
a given mould (and from one mould to another) and that the sequence
of the distances between chainlines can identify the sheets produced in
a single mould. Although for various reasons a given space may not be
consistent in all those sheets, the variation is slight and the overall pattern
is not affected.

In describing books printed on handmade paper, therefore, it is not
sufficient simply to say, for example, "chainlines 23 mm. apart." Instead,
the whole sequence across a sheet ought to be recorded, and Vander
Meulen has supplied a system that bibliographers should adopt. He uses
vertical lines to separate chain-space measurements (extending the prac-
tice Stevenson follows near watermarks), with three further conventions:
parentheses indicate an estimated or incomplete measurement (at a gut-
ter or when a sheet was cut between chainlines); ellipsis dots signify an
incomplete sequence (for a partial sheet); and the percentage sign stands
for a deckle edge (in parentheses when the deckle is inferred). A record
(with measurements to the nearest half-millimeter, taken at the middle of
the sheet) might look like this:

(9) | 19 | 29.5 | 27.5 | 31 | (29) | 29.5 | 30 | 28.5 | 20 | (13)

(One desirable modification suggested by John A. Lane is to use a verti-
cal wavy line instead of the percentage sign: see "Arthur Nicholls and
His Greek Type for the King's Printing House," The Library, 6th ser., 13
[1991], 297–322 [p. 318].) When there is a watermark, its position in
the sequence should be shown, using Stevenson's system (explained in
my essay); and the sequence should reflect the sheet as viewed from the
mould side with the watermark right side up (the standard orientation for
bibliographical use: see below for Needham's use of it). Obviously one


39

Page 39
could also view the paper from the felt side, but it usually seems easier
to work with the side showing the obverse of the image. When a water-
mark is not present, the orientation is not significant, since the sequence
serves its purpose whether read forward or backward. The great value of
giving all the chain-space measurements is that all handmade papers can
thereby be identified, even when they have no watermarks or when only
an unwatermarked part-sheet is present (as in some half-sheet gather-
ings). In the first of the two sample descriptions near the end of my es-
say, the identification of the watermark and countermark should include
only the height and width measurements and should be followed (after a
semicolon) by the chain-space sequence, incorporating a notation of the
water mark position.

The most extensive use, thus far, of Vander Meulen's observations
has been made by David L. Gants and R. Carter Hailey. Although their
methods of collecting data differ (Gants's is high-tech and Hailey's low-
tech), they both make chain-space sequences the center of their paper
descriptions—accompanied by indications of wireline density (see below)
and measurements of watermarks, with digital photographs (Gants) or
freehand drawings (Hailey) of the watermarks. Both follow Vander Meu-
len's plan of using vertical lines to separate chain-space measurements,
but each makes some modifications. Gants, when explaining his approach
to building a database, says that he records the sequence for every sheet
(not a representative one for any sheet from the same mould) and that he
takes his measurements from either side of the watermark (not the center
of the sheet), as a location accessible in a variety of formats. See "Identi-
fying and Tracking Paper Stocks in Early Modern London," in Papers of
the Bibliographical Society of America
, 94 (2000), 531–540. However, in his
online "A Digital Catalogue of Watermarks and Type Ornaments Used
by William Stansby [1614–1618]" (2005), he does not report the sequence
for each sheet individually, and he gives two chain-space sequences per
mould, from the "top" and "bottom" of the sheet (that is, near the two
longer edges, when the watermark is viewed in upright position). He also
uses different symbols from Vander Meulen's: parentheses for chainlines
that intersect watermarks, braces for deckle edges, double slashes for gaps
in measurement, and square brackets for trimmed edges. Hailey makes
fewer alterations to Vander Meulen's form of report, the chief one being
to print in bold-face italics the figures for the space(s) where a watermark
is located; and each of his chain-space measurements is an average of the
measurements from several sheets, the result being a "composite chain-
space model." (In using this approach, one must be careful not to obscure
differences between paper stocks.) His method is set forth in detail on
pp. 156–165 of "The Shakespearian Pavier Quartos Revisited" (Stud-
ies in Bibliography
, 57 [for 2005–06; 2008], 151–195); he had previously


40

Page 40
described his approach less fully in "The Bibliographical Analysis of An-
tique Laid Paper: A Method" (in Teaching Bibliography, Textual Criticism,
and Book History
, ed. Ann R. Hawkins [2006], pp. 149–154) and in "The
Dating Game: New Evidence for the Dates of Q4 Romeo and Juliet and
Q4 Hamlet" ( Shakespeare Quarterly, 58 [2007], 367–387 [see pp. 372–373,
376–377]).

Vander Meulen's 1984 essay also discusses several other ways to iden-
tify paper, none of which is covered in my essay. Their inclusion in a
bibliographical description, however, is not necessarily required. The one
most likely to qualify is a measurement of wireline density—expressed (as
Vander Meulen suggests) in the number of wires per three centimeters.
(A recent use of the three-centimeter measurement, reported to me by
Vander Meulen, occurs in Agnieszka Helman-Ważny's The Archaeology of
Tibetan Books
[2014], as on pp. 35, 177, and 231–248.) Since paper can
be identified by the chainline sequences alone, the addition of wireline
density may not be of further help, though it can sometimes be useful
in making tentative discriminations among paper varieties and in deter-
mining which varieties come from the same pair of moulds. In any case,
a thorough description is of course not limited to details necessary for
identification, and the inclusion of wireline density obviously adds to the
completeness of the description. Another identifying characteristic is the
precise location of any tranchefiles (a tranchefile is an extra chain that
sometimes occurs, at one or both ends of the mould, between the last
regular chain and the frame of the mould); but since these lines would
be part of the records of chain-space sequences (and recognized by the
smaller intervals they usually create), they do not normally need separate
attention.

Still another feature of laid paper is the "shadow" centered on many
chainlines, caused by the supporting wooden ribs under the chains (ex-
cept for most tranchefiles). Sometimes, apparently when chains are not
directly aligned over the ribs (as they normally are), there is an effect of
double chainlines, one of which in each pair is less distinct than the other.
Vander Meulen does not include these secondary chainlines in his chain-
space sequences, nor does he report the location of shadows in relation to
the secondary chainlines. Although the presence of these features should
perhaps be mentioned in general terms in a bibliographical description,
they do not usually call for detailed reporting. A further article of Vander
Meulen's, published four years after this major one, should be mentioned
here as a footnote to it: "The Low-Tech Analysis of Early Paper" (Literary
Research
, 13 [1988], 89–94), which conveniently sums up the techniques
for analyzing paper and the literary and historical uses to which such
analysis can be put.

Paul Needham has published an important series of essays on the
history of paper and the analytical uses of paper evidence. Of these, the
two that are perhaps most directly relevant to bibliographical descrip-
tion are "The Paper Supply of the Gutenberg Bible" (Papers of the Biblio-
graphical Society of America
, 79 [1985], 303–374) and "Allan H. Stevenson
and the Bibliographical Uses of Paper" (Studies in Bibliography, 47 [1994],
23—64). The former includes the following example of a form for record-
ing a paper stock (p. 317), which is repeated with further explanation and
commentary in the latter (pp. 32—33, and with the addition of the "a"
and "b"):

Royal: Bull's Head

a. mR4 | 19 | 14 chains (ave. 42.1 mm) | 18 | (6+)

b. mL4 (3+) | 21 | 14 chains (ave. 42.3 mm) | 18 | (1+)

The heading shows the common name for the size of the sheet (Royal),
along with a descriptive term for the type of watermark (Bull's Head),
without further specification of the dimensions of either one. Needham
feels that precise leaf measurements of handmade paper are not useful
even for an example with surviving deckle edges, given the variations that
would exist between measurements taken at different points and the dif-
ficulty of estimating how much is inaccessible in the fold. As long as the
approximate nature of such measurements is clear, however, there is no
harm in providing them as evidence for the extrapolation to the named
size. The "a" and "b" lines in the description refer to the twin moulds of
the particular paper stock; and "mR" and "mL" give the location of the
watermark as being in the right or left half of each mould, with the at-
tached number indicating which chain-space it is in (here, the fourth from
the nearest short edge). For "right" and "left" to be meaningful, of course,
the paper must be consistently viewed from the same side and with the
watermark image upright. Needham recommends looking at the mould
side; and if in certain instances the felt side seems more appropriate, the
designation "(f.s.)" can be added. When a watermark design has no obvi-
ous top or bottom, the position of some arbitrary feature can sometimes
be used and noted (though totally symmetrical abstract designs defeat the
system altogether).

The remainder of each "a" and "b" line gives, at each end in paren-
theses, the distance from the deckle edge to the tranchefile; then, moving
in from each end, the number between the vertical rules is the measure-
ment from the tranchefile to the nearest regular chain; and finally, in
the center, is the number of chainlines with the average distance be-
tween them. (One possible ambiguity—whether or not the stated num-ber of chains includes the two apparently represented by the second and


42

Page 42
third vertical lines—could be avoided if reference were made to "chain
spaces" and not to "chains.") Needham acknowledges that this statement
of chainline numbers is "a very crude 'measurement,'" but he believes it
is usually sufficient for paper-stock identification when used in conjunc-
tion with the other details. He recognizes, however, that noting the size
of every chainline interval, as suggested by Vander Meulen (see above),
may sometimes be needed, especially in connection with unwatermarked
paper. The tabular form of Needham's presentation is obviously not es-
sential: his notation can be made to fit within the general scheme I sug-
gested at the end of my essay.

One notices that Needham's description does not include an indi-
cation (using Stevenson's system or any other) of the exact position of
a watermark in relation to the adjacent chainlines. The reason is that
Needham feels the information conveyed by such measurements is
"so inferior to that supplied by actual-size reproductions" that he can-
not regard them as "a fundamental element of paperstock description"
(p. 34)—though he notes that they can indeed be helpful, as Vander
Meulen has shown. In any case, reproductions cannot always be sup-
plied; and, even when they are, some bibliographers will feel that they
should be supplemented by measurements. But it is true, of course, that
reproductions will always provide details not covered by verbal accounts.
Needham's essay on Stevenson includes other criticisms, but they are
subordinate to the admiration expressed for Stevenson's overall achieve-
ment. Reading Needham's assessment of Stevenson should be an impor-
tant part of any bibliographer's preparation for thinking about paper.
Several other essays of his also make basic contributions to this process:
"Res papirea: Sizes and Formats of the Late Medieval Book," in Ration-
alisierung der Buchherstellung im Mittelalter und in der frühen Neuzeit
, ed. Pe-
ter Rück and Martin Boghardt (1994), pp. 123–145; "Concepts of Paper
Study," in Puzzles in Paper: Concepts in Historical Watermarks, ed. Daniel
W. Mosser, Michael Saffle, and Ernest W. Sullivan II (2000), pp. 1–36;
and his superb survey "The Paper of English Incunabula," in Catalogue of
Books Printed in the XVth Century Now in the British Library
, ed. Lotte Hel-
linga (2007), pp. 311–334.

B. J. McMullin's articles of 2003–04, 2004, and 2008 (cited above,
under "Format") are basic for the study of handmade wove paper in
the late eighteenth and early nineteenth centuries and machine-made
paper in the first half of the nineteenth century. They provide historical
background and explain some analytical techniques applicable to those
papers. In addition to outlining clues regarding format (see "Format"
above), he shows (in the 2008 paper) how seam marks in machine-made
paper can be used for dating (paper with seam marks is probably between
1810 and 1850) and for identifying cancels and other irregularities in the


43

Page 43
makeup of a gathering (signaled by any breaking of a seam-mark pat-
tern). An unanswered historical question that hampers some analysis is
whether the printer gathered and collated sheets before sending them to
the binder or whether, in the era of publishers' bindings, the binder took
on this job; if the latter, random combinations of part-sheets in finished
books might be more likely, thus rendering more doubtful the determina-
tion of the particular imposition used. The point most relevant to writing
a bibliographical description is his suggestion of two alternative plans for
recording seam marks (pp. 78–79):

seam marks horizontal: B1 2 7 8 F3 4 5 6 H3 4 5 6 M1 2 7 8

seam marks vertical: C5 8 G6 7 K6 7 N5 8 R1 4 U2 3 Z2 3

seam marks horizontal: $1 2 7 8 BM, $3 4 5 6 FH

seam marks vertical: $1 4 R, $2 3 UZ, $5 8 CN, $6 7 GK

As he points out, however, the pattern will not necessarily be the same in
every copy of the edition; and if one therefore inserts library sigla (or copy
numbers) in parentheses to identify individual copies, he feels that the first
system would probably be clearer—though I believe that the preferable
one might vary in different situations, since each has a different focus.
In any case, they are both usable; and, though other schemes could be
devised (especially to give more information about the exact positioning
of the seam marks), there would seem to be no reason in most instances
to do so.

I do, however, think there is reason to question the point McMullin
makes next: that "one might well allow the record to stand unqualified
[with copy sigla], to be understood as indicating that a seam mark of a
particular orientation is to be found in the specified gathering in at least
one copy from within the edition." One could, of course, adopt an ab-
breviated form of paper description and omit the locations of seam marks
entirely (saying simply "machine-made paper with seam marks"); but if
one is going to specify a sample location, the copy (or copies) used to
obtain that information should be specified. The situation is analogous to
the recording of locations of other features that vary from copy to copy.
In the case of handmade paper, for example, all the sheets of a book may
have the same watermark and countermark, but those marks may not
appear on the same leaves in every copy, depending on how the paper
was turned before printing and how the printing and handling of half-
sheet gatherings were carried out; furthermore, the small variations in the
papers coming from twin moulds (variation in watermark placement and
in chainline and tranchefile spacing) may not be identically distributed in
every copy. In all such cases, therefore, one ought to cite not only signa-
ture locations but also the specific copies used—and normally to do so in


44

Page 44
the basic description, rather than including the information in the list of
copies examined (see "Arrangement" below), since what is being recorded
is a feature of the edition as published, not a post-publication alteration.
A justifiable exception to this last recommendation, however, can be illus-
trated by Stanley Boorman's bibliography of Ottaviano Petrucci (2006),
where he (remarkably) records the locations of watermarks throughout
each copy examined (that is, not simply sample locations); this information
(along with his thorough notes on other variable features, such as in-house
corrections) is much more efficiently placed in the accounts of examined
copies, which thus form the largest element in his descriptions.

One other matter that McMullin has written about is the paper-quality
mark—the symbol that may appear in the direction line on the first page
of a gathering to identify the paper when two issues on different papers
are produced. The presence of such marks should obviously be noted in
the paragraph on paper in a description. An example of these marks is
illustrated by McMullin in What Readers Should Ignore on the Printed Page
(2014), p. 7; see also his "Paper-Quality Marks and the Oxford Bible
Press, 1682–1717," The Library, 6th ser., 6 (1984), 39–49, and "Cowper's
Complete Poetical Works, 1837 (Russell, 166)," Script & Print, 40 (2016),
45–54 (esp. pp. 51–53).

John Bidwell's contributions deal primarily with the history of pa-
permaking and thus provide useful background for descriptive bibliogra-
phers, even if they are not always relevant to the practice of description.
(For an excellent overview, see especially his "The Study of Paper as
Evidence, Artefact, and Commodity," in The Book Encompassed, ed. Peter
Davison [1992], pp. 69–82.) But descriptive bibliographers will be glad
to find in his extraordinary American Paper Mills, 1690–1832: A Directory of
the Paper Trade, with Notes on Products, Watermarks, Distribution Methods, and
Manufacturing Techniques
(2013) a list of watermark attributions, citing each
watermark and naming the mill that used it (pp. lxx–lxxiii). They will also
be happy to find in "The Size of the Sheet in America: Paper Moulds
Manufactured by N. & D. Sellers of Philadelphia" (Proceedings of the Ameri-
can Antiquarian Society
, 87 [1977], 299–342) a table headed "Some Names
for Anglo-American Paper Sizes and Their Measurements." What makes
this table more useful than others of its kind is that, for each of fifteen
named sizes, the dimensions reported at nine specified times (from 1713
to 1952) are given.

Bidwell's principal exercise in actual description of paper occurs in
his Fine Papers at the Oxford University Press (1999), where (after an excel-
lent historical account of the manufacture and sale of handmade paper)
he provides fascinating commentaries on the forty specimens that are
included in the book. Besides identifying these papers, he gives a concise


45

Page 45
description of each one, citing primarily the characteristics that the Press
would have recorded in its ledgers (but recognizing that such descriptions
did not have to be self-sufficient because papermakers would have been
shown samples of what was desired). Each of his descriptions consists of
seven elements: weight (per ream of 480 sheets), texture (laid or wove),
dimensions, substance (grams per square meter), thickness (caliper mea-
surements in thousandths of an inch), color, and watermark. Here is an
example: "28–pound hand-made antique laid, 16¼ × 22½ ins: 106 gsm,
caliper .005 in., cream, watermarked near each of the four corners: W [flower]
M (felt side)" (p. 46). Clearly two of these features, weight and substance,
could not be reported from direct observation in descriptions of books
since they require loose sheets (though they might be provisionally noted
from external sources); but the other five are part of the standard I sug-
gested in 1971, though presented differently. Bidwell recognizes that the
thickness of a sheet of handmade paper is likely to vary from one part
of the sheet to another, and thus the significance of the thickness figures
he gives is not clear (a point made by David L. Vander Meulen in his
review of this book in Papers of the Bibliographical Society of America , 97
[2003], 589–595). In my 1971 essay I suggested that such figures should
be expressed either as a range or as an average; I would now add that,
in the latter case, the word "average" or the abbreviation "avg." should
be appended to emphasize the status of the figure. (An article that may
be regarded as a supplement to Bidwell, though published earlier, is John
Purcell's "The Availability of Hand-Made, Mould-Made and Fine Ma-
chine-Made Papers," Matrix, 3 [1983], 67–75, which includes a three-
page table giving specifications for twenty-nine papers that were available
at that time.)

One of Bidwell's services to descriptive bibliographers is to have writ-
ten a thorough review of Peter F. Tschudin's Grundzüge der Papiergeschichte
(2002) for Papers of the Bibliographical Society of America (98 [2004], 105–
109). Because Tschudin recommends describing paper and watermarks
in terms of the International Standard for the Registration of Paper with or
without Watermarks
(first proposed by the International Association of Pa-
per Historians [IPH] in 1992 and last revised in 2013 [text available on
the IPH website]), Bidwell had occasion to assess that system—a task
that most bibliographers have not undertaken. The system is designed to
produce machine-readable records, each of which has potentially a hun-
dred fields, sometimes involving intricate coding. As an example, Bidwell
notes that a watermark consisting of a crown over CLK in script would
be reported as "R3/1—{b:(i:X"CLK")}"—and this is far from being one
of the more complex possibilities. Although a large database constructed
in this way could indeed be searched productively, the effort involved in


46

Page 46
writing such descriptions is a deterrent to their widespread use. Bidwell
comes to the sensible conclusion that descriptive bibliographers may justi-
fiably feel that their purposes are adequately served by readily understood
verbal watermark descriptions (including, as Stevenson suggested, quasi-
facsimile transcriptions).

A more detailed criticism of the IPH system (referred to by Bidwell)
has been provided on the website produced at Bates College by Robert W.
Allison and James A. Hart, "The WWW Watermark Archive Initiative,"
which is aimed at developing guidelines for online databases: see the sec-
tion entitled "Commentary and Interpretation of the IPH Standard." In
their comments on watermarks, they say, "Our objective is to use straight-
forward standardized language and eliminate the codes." This website
also contains links to several online databases of watermark images, such
as the University of Delaware's "Thomas Gravell Watermark Collection,"
containing some 8500 records as of early 2015; and the IPH website lists
more than a dozen such links. (See below for some further references to
discussions of online databases.)

The next year after my essay, Philip Gaskell (whose important earlier
studies of paper are mentioned there) published A New Introduction to Bib-
liography
(1972, 1974), which discusses the history and analysis of paper in
two chapters. The one on paper in the hand-press period (pp. 57–77) has
a page on description (pp. 76–77), and that on the machine-press period
(pp. 214–230) has two pages (pp. 226–228). The former chapter includes
the point, which cannot be stated too often, that handmade paper varies
from sheet to sheet and that any edition may have been printed on two or
more paper stocks, which may not be consistently represented in a given
copy (emphasizing once again the necessity for examining a large number
of copies). But the main contribution to paper description that Gaskell
makes in this book has to do with machine-made paper. He enumerates
five simple tests for distinguishing the characteristics of different stocks:
(1) assess the feel (surface texture) and color in a good light; (2) identify,
with a raking light, the belt side and notice the wove pattern; (3) measure
the pattern (in wires per centimeter) and, if it is oblong or diamond-shaped
(rather than square), notice whether its longer dimension is parallel to
the grain (which is also the machine direction); (4) measure the thickness
with a micrometer; and (5) establish the relative densities of papers in two
books by weighing them (though it should be added that there are often
too many variables here to make this test of much use). He then lists seven
additional tests that, because they involve damaging the paper (by fold-
ing or applying chemicals), would not normally be of use to descriptive
bibliographers. Tables of standard paper sizes are given for the hand-press
period (pp. 73–75; provided in my essay as well) and the machine-press


47

Page 47
period (p. 224). (A short list of handmade paper sizes also appears in J. D.
Fleeman's bibliography of Samuel Johnson [2000], p. xxxvii.)

Besides Gaskell, another summation of basic information about pa-
per (far more extensive than Gaskell's), incorporating original research
and with fresh observations, is Neil Harris's Paper and Watermarks as Bib-
liographical Evidence
(2010, 2017, on the website of the Institut d'Histoire
du Livre in Lyon; a pdf of the second edition can be printed out as a
document of 155 very full pages). It is a learned treatise on many aspects
of paper study, presented in a "snappy" and "punchy" way (his words),
with frequent jocular asides. (This style is not to everyone's taste, but
the work does contain some memorable sentences.) The most relevant
parts for descriptive bibliographers are embedded in the fourth and fifth
chapters: "The Shape of Paper" (pdf pp. 32–44), which deals with size
and format; and "Dillying and Dallying with Watermarks" (pp. 45–59),
which includes comments on describing, reproducing, and classifying
watermarks. Bibliographers who have occasion to consult published col-
lections of watermark designs will benefit from the fascinating chapter on
Briquet (pp. 60–75), which takes up his life, methods, and followers, as
well as how to employ his great work. In using any of Harris's discussions,
one would be well advised to read, at the same time, the corresponding
sections of his impressive seventy-page analytical record of the interna-
tional literature, full of references not easily found elsewhere and advice
not available anywhere else—see especially sections 7–23 (pp. 112–131,
on size, format, and watermark description and reproduction), 30–31
(pp. 136–144, on analytical bibliography and watermark collections), and
35 (pp. 150–152, on websites).

What may be regarded as a supplement to Gaskell's and McMul-
lin's work on nineteenth-century paper is Chris Elmore's "Describing
Nineteenth-Century Papers" (Script & Print, 40 [2016], 5–28), though
its emphasis is on writing papers rather than printing papers (it should
certainly be consulted by those dealing with handwritten letters and
journals). Of the points relevant to bibliographers of printed books, two
are worth repeating here, even though they are obvious to anyone who
understands that paper made with the Fourdrinier machine has a wove
pattern, imparted by the moving woven-wire belt on which the pulp is
placed, and that any chainlines or watermarks result from the action of a
dandy roll pressing into the other side of the pulp. Knowing this process,
one can tell whether paper with a laid pattern is machine-made by noting
whether it has a wove pattern as well as a laid pattern—the former of
course indented into
one side of the paper, and the latter indented into
the other. (The indentations from the wove belt were deeper and closer
together than those resulting from hand-held moulds, but this point,


48

Page 48
being comparative, is difficult to make use of.) Second, machine-made
watermarked paper (even without laid lines) can naturally be detected
by the presence of the watermark indentations on the opposite side from
the wove-pattern indentations; but one can also note that the indenta-
tions of the lines of the watermark design (and lettering, if any) are inter-
sected by the indentations of the wove pattern from the belt—whereas
in handmade wove paper the watermark, being on top of the wire mesh,
covers the mesh pattern at the points of contact. (One must recognize
that these facts about paper made with the Fourdrinier machine do not
apply to so-called mechanical mould-made paper, in which a rotating
cylinder mould deposits each sheet on a moving woolen felt, and in which
all patterns and watermarks are therefore indented from the same side;
another difference between such paper and Fourdrinier paper is that its
fibers are distributed randomly in the sheet rather than solely in the belt
direction.) Employing contemporary paper-trade sources, Elmore says
that "laid" and "wove" were the standard nineteenth-century terms for
printing papers. As for dimensions, he gives tables of writing-paper sizes
(and size names), but he does not add anything to Gaskell's table of ma-
chine-made paper sizes. Although he suggests that bibliographers might
use some of the trade terms for other characteristics (such as finish, bulk,
and opacity), he also indicates that they were somewhat impressionistic,
reflecting the judgment of professionals who handled paper every day,
and that they should therefore be used with caution—or, I would add,
probably not be used at all (or only as ordinary adjectives, not as techni-
cal terms).

Among the many other post-1971 publications on the history and
analysis of paper, several may be mentioned as particularly useful for
descriptive bibliographers (and see the references in "Format" above).
Published collections of watermark reproductions have improved since
1971 as a result of the use of beta-radiography and several photographic
and digital processes. (See David E. Schoonover, "Techniques of Repro-
ducing Watermarks: A Practical Introduction," in Essays in Paper Analysis,
ed. Stephen Spector [1987], pp. 154–167; A. de la Chapelle, C. Monbeig-
Goguelle, and A. Prat, "Les filigranes des dessins anciens et les relèves
betaradiographiques," Annals of Radiology, 37 [1994], 249–258; David L.
Gants, "The Application of Digital Image Processing to the Analysis of
Watermarked Paper and Printers' Ornament Usage in Early Printed
Books," in New Ways of Looking at Old Texts, II, ed. W. Speed Hill [1998],
pp. 133–147; and Neil Harris, Paper and Watermarks as Bibliographical Evi-
dence
[2017], pp. 54–57, 128–131.) For example, there are Thomas L.
Gravell and George Miller's two volumes (A Catalogue of American Water-
marks
, 1690–1835 [1979; rev. with Elizabeth Walsh, 2002] and A Catalogue
of Foreign Watermarks Found on Paper Used in America, 1700–1835
[1983]);

see the related article by Daniel W. Mosser and Ernest Sullivan II, "The
Thomas L. Gravell Watermark Archive on the Internet," in Puzzles in
Paper: Concepts in Historical Watermarks
, ed. Mosser, Sullivan, and Michael
Saffle (2000), pp. 211–228. A notable publication by a great cartographic
scholar, David Woodward, is his Catalogue of Watermarks in Italian Printed
Maps ca. 1540–1600
(1996). A number of collections of watermarks are
now available online, and two websites that conveniently provide links to
many of them are those of the International Association of Paper Histo-
rians and of the "Bernstein: The Memory of Paper" consortium; see also
Harris (cited three sentences earlier), pp. 150–152.

The two anthologies just cited, Spector (1987) and Mosser (2000), in-
clude a number of other pieces relevant to the description and recording
of watermarks. The Spector contains Phillip Pulsiano's extremely use-
ful list, "A Checklist of Books and Articles Containing Reproductions
of Watermarks" (pp. 115–153). The Mosser presents three articles on
watermark reproduction: Carol Ann Small's "Phosphorescence Water-
mark Imaging" (pp. 169–181), Rolf Dessauer's "DYLUX, Thomas L.
Gravell, and Watermarks of Stamps and Papers" (pp. 183–185), and Dan-
iela Moschini's "La Marca d'Acqua: A System for the Digital Recording
of Watermarks" (trans. Conor Fahy; pp. 187–192). Also in the Mosser
is Robert W. Allison's "An Automated World Wide Web Search Tool
for Papers and Watermarks: The Archive of Papers and Watermarks in
Greek Manuscripts" (pp. 201–210), which describes the Bates College
archive mentioned above; and Ted-Larry Pebworth's "Towards a Tax-
onomy of Watermarks" (pp. 239–242), which offers a computer-oriented
system based on a "flexible grid pattern" for describing locations of parts
of watermarks.

A third anthology, Looking at Paper: Evidence & Interpretation, ed. John
Slavin et al. (2001), emphasizes paper in prints, drawings, and manuscripts
and has less of relevance for descriptive bibliography; but it does include
Ruby Reid Thompson's "Historical and Literary Papers and the Applica-
tion of Watermark Descriptions" (pp. 142–153), which makes use of the
Nottingham University Library Watermark Database, and Ian Christie-
Miller's "Digital Imaging" (pp. 139–141), on the "Bookmark" reflected-
light system. A later article on Christie-Miller's approach is his "New
Tools for Old Paper" (The Book Collector, 58 [2009], 383–389), which
describes his Advanced Paper Imaging System, using both frontlighting
and backlighting and showing conjugate leaves together. The equipment
that Christie-Miller has devised is illustrated on his website (www.early-paper.com); the battery-powered one-millimeter-thick electroluminescent
source for viewing paper structure and watermarks, which is a part of
his system, has been marketed as "Pocket Viewlight" by Howard Eaton
Lighting Ltd.

The series of articles reporting on the use of the Davis (California)
cyclotron to analyze the makeup of paper and ink is most conveniently
represented by Richard N. Schwab, Thomas A. Cahill, Bruce H. Kusko,
and Daniel L. Wick's "Cyclotron Analysis of the Ink [and paper] in
the 42–Line Bible," Papers of the Bibliographical Society of America , 77
(1983), 285–315. Two good general articles on the usefulness of water-
mark evidence, both published in 1978, are Bruno Scarfe's "A Role for
Watermarks in Bibliographical Description, with Special Reference to a
Collection of Spanish Dramatic Items," Bibliographical Society of Australia
and New Zealand Bulletin
, 12: 85–101; and Stephen Spector's "Symmetry
in Watermark Sequences," Studies in Bibliography, 31: 162–178. Further
references can be found in my Introduction to Bibliography (2002 revision),
part 5, pp. 181–193, and sections 9D5, 9F2, 9G5, and 9H4 (pp. 205–207,
290–291, 307–309, and 314).

To summarize: the main points to be added to my 1971 recommenda-
tions are that one would be well advised to record the sequence of chain-
line intervals in a stock of paper; that any indication of the location of a
watermark should specify which half of the sheet it is in; that any citation
of a given leaf as a source of evidence should indicate the particular copy
of the book used; and that specifications of thickness of handmade paper
should note that the figure is an average. These additions will make the
treatment of paper both more comprehensive and more precise.
