Fiander Sent: Wednesday, May 01, 2013 10:35 AM To: CODE4LIB@LISTSERV.ND.EDU Subject: [CODE4LIB] When did OCLC's original xISBN service launch? According to the Code4Lib mailing list archives, the service moved from "experimental" to production, and changed format, in February, 2007, but the earliest reference to the service in the archives is a question from Thom Hickey in May, 2005 soliciting feedback about what additional features might be of interest. - David
