The aim of the WikiProject Libraries is to define a structure for libraries and to create and improve the items about library.

Libraries on Wikidata[edit]

There are currently 19958 libraries with Wikidata items (Nov 2018). Quick query

See it in Wikidata Query Service

TO BE DONE One of the aims of this project should probably be to improve the level of precision with which we are classifying libraries on Wikidata. From the chart above, we can see that a majority of libraries are still classed simply as instance of (P31) library (Q7075). Below is a list of possible statements that could be used to improve the classification: Instance of (P31):

  • Public Library (Q28564)
  • Academic Library (Q856234)
  • College Library (Q1622062)
  • Research Library (Q1438040)
  • National Library (Q22806)
  • Medical Library (Q6150991)
  • Scientific Library (Q2586205)
  • Special Library (Q385994)

Please feel free to add to the list.
