  We analyse the number of pages of novels (i.e., fictional
  literary works) in the German National Library (DNB).


  It is not trivial to extract all novels from a big
  catalogue like that of the German National library.
  “Librarians estimate that genre information is present in
  the expected MARC field for less than a quarter of the
  volumes in HathiTrust Digital Library,” (Underwood et al.
  2013) and we encounter the same problem, which calls for
  an innovative solution.


  Our approach is to

  1. extract a list of writers from Wikidata together with
  their GND id

  2. download linked data about the DNB books

  3. join the writer list with the list of books using the
  GND id


  This repository documents the evolution of this process,
  which turned out to be not as straightforward as it seems.
  One reason is the size of the data and the complexity of
  queries.
