Here are some thoughts about what we might do next with our xISBN service (see http://www.oclc.org/research/projects/xisbn/ and http://www.oclc.org/research/projects/xisbn/technical.htm): * ISBN to author/title * Adding 'distinctive' information to the response to help selection * xOCLC: take in an OCLC number and return the OCLC numbers in its FRBR work-set * xLCCN: do the same thing for LCCNs * xISSN: do the same thing for ISSNs * SOAP wrappers around everything * Expose it all via OpenURL 1.0 Any ideas about what you would use? Something else along these lines? --Th Blog: http://outgoing.typepad.com/
