Exceptions to W1 Classification

  • Serial government publications that are administrative or statistical in nature are classed in W2, along with ongoing reports about multiple hospitals under government administration
  • Serial hospital publications that are administrative or statistical in nature, including reports of single government hospitals are classed in WX 2
  • Other non-periodical serials may be classed by topic when the classification schedule specifically says the number may be used for both monographs and serials. This most commonly occurs for specific publication types, such as directories, handbooks, dictionaries, legislation, etc.

Numbered Congresses

  • Serial publications of congresses were classed in W3 until July 1988, as were ongoing named, numbered, and dated monographic congresses
  • All newly acquired serial publications that are proceedings or reports of meetings are now classed in W1. All newly acquired monographic congresses, including those ongoing named meetings previously classed in W3 are now classed in the appropriate subject classification number
  • W3 is still used for individual volumes in serial analytics that were assigned a W3 call number prior to 1988
