Paper
It is important that paper measurements be provided, according to the model Tanselle recommends in "The Bibliographical Description of Paper," SB 24 (1971): 27 — 67. Since the paper used in periodicals of the machine-press era may differ significantly from that used in books, periodicals are likely to provide new insights for researchers who are interested in paper. In general, nineteenth-century paper is not particularly durable, thanks to the introduction of powerful rotary pulp beating machines, the use of chlorine bleach and alum-rosin sizing, and the substitution of wood pulp for rags.[31] Many periodicals (especially those with large circulations) also use thinner, lightweight paper to reduce mailing costs.
Since the discoloration produced by high acidity may make it difficult to determine paper color accurately, the bibliographer may want to comment on the condition of the paper in the copies examined.[32]
