http://142.28.183.110/cgi-bin/koha/forage2 This forage demo is based on the dewey classification subjects available at http://www.oclc.org/dewey/ As I suspected, this list is made available under the following rather onerous license: ============================================================================ Libraries with ongoing subscriptions to WebDewey in CORC or Dewey for Windows may post the DDC21 Summaries (i.e., the first three levels of the Dewey Decimal Classification - for example, 500 Science is Level 1, 510 Mathematics is Level 2, 513 Arithmetic is Level 3) on their web sites solely for the internal, noncommercial purpose of organizing the resources made available to their patrons via such web sites. Such use of the DDC 21 Summaries should be accompanied by the following notice on the initial screen: The Dewey Decimal Classification is 1996-2001 OCLC Online Computer Library Center, Incorporated. Used with Permission. DDC, Dewey, and Dewey Decimal Classification are registered trademarks of OCLC Online Computer Library Center, Incorporated. All other use of the DDC requires prior written permission from OCLC Forest Press. To request a licensing proposal, please send an e-mail message to DeweyLicensing@oclc.org, describing in detail your proposed use of the DDC. ============================================================================ My understanding of this is that we cannot use the list of dewey subject classifications in Koha. I'm even breaking the terms of the license with my little demo here. Also, this list is limited to the top three levels of the classification. (ie 956, but not 956.4). To get the full classification, you need to purchase the DDC21 book at $325 US. The license on this data would undoubtedly be even harsher than that on the first three levels. Steve
