See alsoOCLC control number (P243)


While OCLC control number (P243) is intended to be an identifier for an item in our version (Q3331189) class, the OCLC work ID is intended to be a single identifier for the literary work (Q7725634) itself, encompassing all editions, as set out here: [2]

(NB: be aware that the OCLC's linked data is released under an ODC-BY licence, and therefore cannot be harvested into Wikidata. However, "OCLC identifiers, and Linked Data URIs, are always in the public domain" [3])

Unfortunately, yes. For example OCLC control number (P243) 20626614 maps to a thesis dissertation, Renal biopsy; a review and description of a new technique Jheald (talk) 13:09, 13 June 2018 (UTC)
  • If P243 currently mixes both, wouldn't it be preferable to make two new properties? Eventually P243 could be deleted or be an empty parent property of both.

@Jura1: OCLC control number (P243) doesn't mix both. As I far as I know, it is used entirely for the 'classic' OCLC edition identifier, not for this new 'work ID'. Jheald (talk) 13:51, 13 June 2018 (UTC)
