Page-level metadata is used in Folger digital image databases to describe where the page or pages shown in the digital image are located within the book. In the main Folger digital image database, the page-level metadata appears in the Physical Description field.
Sub-units within books
Signatures are given first, whenever available. If folio or page numbers are also available, they are given in parenthesis after the signature. If signatures are not available, only the page or folio number will be used (without parenthesis).
leaf [signature] [recto/verso]
leaf 2F3 recto
leaf 2Z4 verso (page 184)
- Folio numbers
folio [folio number] [recto/verso]
folio 43 verso
- Page numbers
page [page number]
plate [plate number]
Page-level metadata for plates
- If the plate in question is not part of a series of plates, use the location of the page that the plate is facing, as well as the plate number if one is available:
plate facing leaf [signature] ([page or folio number]): [plate number, if available]
plate facing leaf B2 verso (folio 6 verso): plate 2
- If the plate in question is part of a series of plates, use the location of the page that the plates come after, as well as the location of the plate within the series, and the plate number if one is available. Note: Using "plate after..." is preferable, but "plate before" can be used if necessary.
plate [in brackets, the number of the plate within the series] after leaf [signature] ([page or folio number]): [plate number, if available]
plate  after leaf 2Z4 verso (page 184)
- If the plates are numbered at all, the plate number should be given after the location of the plate:
...: plate [plate number]
plate facing leaf 2B1 verso (page 290): plate VII
- If the plates are folding plates, they should be labeled as such:
folding plate facing ...
folding plate facing leaf I1 verso (folio 30 verso)
- For two-page spreads, give the page-level metadata for both pages, separated by a double-pipe:
[left page] || [right page]
leaf A1 verso (page 2) || leaf A2 recto (page 3)
- If the signature, folio number, or page number printed in the book is incorrect, give it as printed, followed by the correct number in brackets:
[signature/page number/folio number as printed] [i.e. [correct signature/page number/folio number]]
folio *3 recto [i.e. folio *4 recto]
- If the book has multiple parts (and especially if the signatures/pagination restart with each new part), note the part of the book before the signature, etc, separated by a comma.
part [number], [signature/page number/folio number]
part 2, leaf U4 verso
