Bibliographic format (also known simply as "format") refers to the proportional relationship between a full sheet of paper and the folded and cut leaves of a book. For example, a text printed two-up so that the sheet of paper needs to be folded once to make the leaves of a book is in "folio" format. A book printed four-up on a sheet that's folded in half, then in half again, is a "quarto" and so on. Generally speaking, bibliographic format only applies to books from the hand-press era (roughly 1450 to 1830), when books were routinely printed on hand-made sheets of paper.

Confusingly, many of the same terms were used as standard names for paper of various sizes. Even more confusingly, the same terms came to be used as general indications of a book's height, beginning in the 19th century (the "machine press" era). In the context of book height, "octavo" means "little", "quarto" means "ordinary size", "folio" means "big", and "elephant folio" means "huge").

When someone associated with the Folger refers to "a folio," you have to rely on context to know if that means an oversize book, a book in in folio format, or one of the first four editions of Shakespeare's collected plays. Similarly, you have to know from context whether a researcher interested in the "the same work in different formats" is interested in different bibliographic formats, different media types (play, opera, movie, etc.) or different carrier types (DVD, VHS tape, etc.)

Hamnet records for vault material display the bibliographic format in parentheses at the end of the "Description" field, after the book's height (rounded up to the nearest centimeter) when applicable. You can keyword search this portion of the description on Hamnet's "Advanced Search" tab by choosing "Size/Format" from the "Search in" menu. Hamnet records use the "DCRM(B)" abbreviations found in the left-hand column of the chart in this article.

Abbreviations and names for formats include:

DCRM(B)[1] Gaskell[2] Ordinary spoken English Latinate spoken English Other
full-sheet 1⁰ broadsheet, full sheet
fol. 2⁰ folio folio fo., 1/2⁰, f⁰, F
4to 4⁰ quarto quarto 1/4⁰, Q⁰, Q
8vo 8⁰ octavo octavo 1/8⁰, O
12mo 12⁰ twelvemo duodecimo 1/12⁰, D

16mo 16⁰ sixteenmo sextodecimo 1/16⁰, S
18mo 18⁰ eighteenmo octodecimo 1/18⁰, T
24mo 24⁰ twenty-fourmo vicesimo-quarto 1/24⁰

72mo 72⁰ seventy-twomo
96mo 96⁰ ninety-sixmo
128mo 128⁰ one-twenty-eightmo

NB. for search-and-replace updating to DCRM(B) abbreviations:

  • character following the number may be:
    • degree symbol
    • superscript zero
    • superscript lower-case letter "o"
  • be careful of the order of operations, e.g. change "12⁰" to "12mo" before changing" 2⁰" to"fol." or you'll end up with "1fol."
