Bruce Willms, of Metropolitan State University Library (OCLC symbol XOJ), e-mailed me on Friday telling me to look at OCLC record #10000001.
Sure enough, XOJ created a great record (another K-level record) for a CD-ROM titled Information on Demand but missed the traditional "golden record" by mere moments. I can only imagine the groan that went through their tech services area when they updated the record and saw the number. Our sympathies are with you, XOJ!
And an update - since the hundred millionth record was input, OCLC Quality Control has upgraded it to a full-level record, complete with controlled subject headings and Dewey call number.
