ǂc Dimensions and bibliographic format
- Give height of binding or container in centimeters, rounding up to the next centimeter
- Also give width, if
- item is a single-sheet item
- item is wider than it is high
- item's height is at least twice its width
- Give bibliographic format in parentheses after the dimensions , if
- it is a printed textual item from the hand-press period (before 1830 or so)
- it is a printed textual item from the machine-press period (after 1830 or so), and format can be confirmed by visible sewing at the center of gatherings
- presence of signatures without confirmation of sewn gatherings does not bestow sufficient confidence for identification of format
- beware publisher's identification of format, which is usually based on size rather than being an expression of how the original sheet was imposed and folded
- Common bibliographic format abbreviations (see DCRM(B) / RDA for a more complete list)
- (full-sheet)
- (fol.) [RDA = (folio)]
- (4to)
- (oblong 4to) [common in scores]
- (8vo)
- (12mo)
- (long 12mo)
- (16mo)
- (18mo)
- (24mo)
- (long 24mo)
- Make a note about anomalous characteristics of format
- For hand-press items, if chainlines run in the opposite direction because the paper came from a head-to-tail double mold
- For machine-press items, if signatures and actual gatherings (as determined by visible sewing) do not correspond
