Hi CODE4LIB, we would like to add DDC classes to a bunch of MARC records, which contains only LoC Subject Headings. Does anybody know, if a mapping between LCSH and DDC is anywhere existent (and available)? I understood, that WebDewey http://www.oclc.org/dewey/versions/webdewey.en.html might provide such a service, but · we are no OCLC customers or subscribers to WebDewey · even if we were, I'm not sure, if the service matches our needs I'm thinking of a tool, where I can upload my list of subject headings and get back a list, where the matching Dewey classes have been added (but a 'simple' csv file with LCSH terms and DDC classes would be helpful as well- I am fully aware, that neither LCSH nor DDC are simple at all...) . Naïve idea...? Thanks for any clues, Irina ------- Irina Arndt Max Planck Digital Library (MPDL) Library System Coordinator Amalienstr. 33 D-80799 Muenchen, Germany Tel. +49 89 38602-254 Fax +49 89 38602-290 Email: [log in to unmask]<mailto:[log in to unmask]> http://www.mpdl.mpg.de
