The National Library of New Zealand classifies its General music scores collection using the McColvin classification scheme. The Alexander Turnbull Library scores are arranged using an in-house system. At present, National Library cataloguers add McColvin classification numbers to all bibliographic records for music scores, including those for the Alexander Turnbull Library, on the assumption that this information is useful to other libraries. We would like to test this assumption by asking music librarians or music cataloguers for your responses to the following questions: 1. Do you use the McColvin classification for the scores in your library? 2. If the answer to the first question is Yes, do you find it helpful that the National Library of New Zealand includes this classification in all records for published scores? 3. If the answer to the first question is No, what system do you use for classifying your scores? Your responses will help us to decided whether to continue our current practice or to limit our assigning of McColvin numbers to the scores that we arrange by this scheme.
