Policy for Analytics for Sound Recordings
March 2020
Recitals with an orientation toward performer(s) or instrument(s) rather than musical repertoire: If analysis is prohibitive, the cataloger may decide not to analyze.
Recordings which consist of a large number of short excerpts or mostly arrangements may not need analytics. The emphasis may be on a historical period, a musical medium or some other aspect rather than individual compositions.
Popular music and jazz recordings are not analyzed, but a full contents note should be provided. See no. 6 below.
There may be situations in which analytics will be deleted from a record. If another library has provided analytics, retain them if the cataloging has been done by a reputable library, as judged by the cataloger, or if most access points are controlled. If the record contains a large number of access points, many or most of which are not controlled, or represented by an authority record, the cataloger may choose to delete them.
In most cases, analyze any classical recording which has particular local interest (e.g. an ESM composer).
Provide as full a contents note as possible for every sound recording collection. Enhanced content designation (subfields r and t) may be used, but is not required. Include thematic index numbers, opus numbers, parallel titles (esp. those in English) and durations when this information is readily available on the item. For popular music, folk music and jazz statements of responsibility related to contents titles are not necessary in most cases.
Decisions on analyzing or not analyzing any questionable items will be decided on a case-by-case basis by the cataloger, in consultation with a librarian when necessary.
