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 in single, unbound sheets
    • 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); consult supervisor if necessary for confident determination
    • 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
  • Bibliographic format is defined as the proportion of a leaf after cutting, folding, &c., to the original sheet of paper; therefore, a single sheet that is 1/2 (or 1/4, &c.) the size of the original sheet is still a folio (4to, &c.). Take note that the English short title catalogue uses proportional fractions for single sheets and a degree sign to represent bibliographic format. (Do not emulate this practice.)
  • 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 example
    • 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
