Books and manuscripts

These guidelines are based on Wikidata:WikiProject Books, with modifications for this project.

Work items

The work is the creative work made by the author, as distinct from any particular publisher's version of that work (in bibliography, FRBR work level).

Works should be instances of written work (Q47461344) or one of its subclasses. Subclasses particularly appropriate for this project include cartographic work (Q25106976), scholarly work (Q55915575), and historical non-fiction (Q1517777).

For a detailed table of available properties, see Wikidata:WikiProject Books#Work item properties.

Edition items

A particular version or edition of a book (not a particular copy of a book in a library) (FRBR expression/manifestation level). Editions of books should used as sources for references.

Each edition of a book should have a separate Wikidata item. If the content (foreword, afterword, illustration), pagination (page number), publisher, or publication place changes, a new item should be created for that edition. If a book is an identical reprint of a previous edition (no change in the mentioned properties), it does not need a new item.

Editions should be instances of version, edition or translation (Q3331189) or one of its subclasses.

For a detailed table of available properties, see Wikidata:WikiProject Books#Edition item properties.

Exemplar items

An exemplar is a specific copy of a creative work, usually in a library, museum, or private collection. Exemplars of books will generally be instances of individual copy of a book (Q53731850), linked to an edition using exemplar of (P1574). For individual books that are unique editions of a work, the same item may be both edition and exemplar.

For a detailed table of available properties, see Wikidata:WikiProject Books#Exemplar properties.

Manuscript items

Manuscripts are single copies of works. They should always be instance of (P31) manuscript (Q87167), but may have additional instance-of statements.

For a detailed table of available properties, see Wikidata:WikiProject Books#Manuscript properties.

Manuscripts listed in the Catalogue of English Literary Manuscripts 1450–1700 (Q105593113) should have property catalog code (P528) with qualifier catalog (P972) = Catalogue of English Literary Manuscripts 1450–1700 (Q105593113).

Maps

Printed maps may also have work, edition, and exemplar items. These are instances of map (Q4006) or one of its subclasses, map edition (Q56753859), and individual copy of a map (Q63872468). Hand-drawn maps may be instance of manuscript map (Q2353983).
