These qualifications which appeared in earlier lists seem to no longer be critical/relevant:
- Having a degree in music but not one in library science!
- Knowledge of the Dickinson Classification scheme.
- Knowledge of ALA filing rules.
- Knowledge of precise subject heading terminology [e.g., Library of Congress (LC) Subject Headings] while still desirable is not as critical as it once was because of online keyword search capabilities.
- Knowledge and ownership of print bibliographic resources that provide access to contents of collections (e.g., de Charms, Goleeke) less necessary becaue of online searchable contents notes.
- Knowledge of how to check "speaker phasing" - ?!
- Knowledge of in-house binding techniques. Vistafoil, pre-made folders which can accommodate scores and parts, and more sophisticated professional bindery techniques have rendered this knowledge virtually unnecessary.
- Knowledge of specific library collections (libraries that have significant collections of music). WorldCat and other online sources have made this knowledge less critical.
- Knowledge of AACR2 is still important but will diminish as RDA is more widely adopted.
- Knowledge of specific vendors and their contact information is no longer necessary because of availability of such info on the Internet.
