A particular type of staff is required in Popular Music Library of radio corporations. Primarily the staffs have to be qualified musically as one would expect the members of staff in any music library to be. However, an academic music training, which would be suitable for a normal music library, is in itself, not sufficient. Over and above musical knowledge and knowledge of library systems, specialists are needed in the subject of popular music. The library requires subject specialists who are able to identify the music, can advise on the idiom and have a more than superficial knowledge. The subject is vast and it is unlikely that anyone will be schooled in more than two or three aspects of it, but taking all staff together it is possible to provide a fairly comprehensive advisory service to potential users.
