For what it's worth, I would like to express my endorsement of Willy Cromwell-Kessler's earlier interpretation of the BIBCO policy of applying LC classification. As a veteran of NCCP, as well as previous cataloging projects with LC, I am aware of the potential drawbacks of requiring PCC libraries to vet any new cutter numbers, whether for authors, artists, musicians, or other subjects, against LC's shelflist before using them in a nationally-coded record. This could become a time-consuming requirement, and one that is calculated to deter libraries from expanding their PCC contributions. I believe that such a requirement would be counterproductive to the spirit and goals of PCC, which aim to foster creation of high quality records in a timely manner, but without imposing extra obligations on participating libraries. I agree with Willy that the use of the indicator 4 in the 050 should be sufficient indication to libraries that the call number was not assigned by LC, and is subject to change if LC uses and reissues the record. Also, as a cataloging supervisor responsible for high productivity of a thinly-staffed unit, I would feel compelled to discourage catalogers in my library from contributing PCC coded records, if there was an additional obligation to obtain LC approval for any subject cutters new to the classification schedules. I would also hazard a guess that LC staff would be equally reluctant to see such a requirement enforced, given the workloads they already have. I believe that the potential usefulness to all libraries of records coded as PCC and produced in a timely fashion is more important than expending time to ensure that the cuttering complies strictly with the LC shelflist. Further streamlining of the process of proposing new classifications and cutters would certainly ease future compliance with a requirement to strictly follow LC subject cutters, but at present I think the goals of PCC are better served by following Willy's initial interpretation of the BIBCO call number policy.
