Notes on source itemsEdit

Because I find the WikiData:WikiProject Books and WikiData:WikiProject Periodicals pages quite verbose in explaining the expected structure of source items. Below is my personal reference summary.


w:Functional Requirements for Bibliographic Records.

  1. The work itself (e.g. Harry Potter and the Philosopher's Stone (Q43361)).
  2. An expression of the work (e.g. the original version and a version with all typos fixed are two different expressions).
  3. A manifestation of an expression (e.g. if the original version was published by two different companies then those are two different manifestations).
  4. An instance of a manifestation (e.g. the library has 2 copies of the manifestation from publisher 1).


Recognise that a book (Q571) is an instance of the "edition item". An e-book (Q128093) is a bit more tricky as I believe it could be argued to be multiple editions (if an e-book is updated is it still the same edition?).


I'm unsure about books with multiple "volumes". See Wikidata_talk:WikiProject_Periodicals#Editions_of_volumes.
