Text Paper: The type of paper upon which the
text in a specific book is printed, assuming that the same paper type has been used for
all text-printed pages. The term is used when there is a need to distinguish the text paper
and the other paper portions of a book such as the plates, endpapers, covers, etc.
Textblock: The part of a book, consisting of all and only
the sewn or glued Signatures

The procedure differs from that used to insert a
Cancel Leaf where glue is applied
to a stub created from an existing leaf, but it is accomplished in two ways. In the case of leaves or
errata slips, a thin line of glue attaches the insert directly to the inner margin of the appropriate text page.
Plates can be inserted in this manner, but are more often found attached along their upper edge to a
blank page larger than the plate itself.
Tissue Guards: Commonly in the 19th century, and to a
lesser extent thereafter, some publishers placed a protective thin
Leaf of tissue-like paper between a
Plate and the opposing page. Some books
may have all plates so protected, or only the
Frontispiece. Most tissue guards are
blank, but occasionally they are found with a printed caption about the plate. A book missing one or
more tissues guards is a very minor defect generally ignored by collectors.
Trigesimo-segundo (32mo): A book size designating a book up to 5" tall. Abbreviation 32mo.
