The Effectiveness of Keyword Searching in the Retrieval of Musical Works on Sound Recordings |
| |
| Abstract: | Three methods of access to musical works on sound recordings are: name-title added entries; title added entries; and contents notes, which may allow access to works through keyword indexes. The purpose of this research was to learn about the comparative effectiveness of standard OPAC retrieval techniques utilized to retrieve sound recordings of musical works. A sample of recorded musical works was searched in CLIO (Columbia Libraries Information Online). The number of musical works per sound recording, and the work's type of title were tested as influencing factors in the success of various retrieval techniques. Retrieval-set sizes, and the number of steps required to locate a target record were also measured for each of the retrieval techniques. Keyword retrieval is shown to be effective. The comparable effectiveness of keyword searching with conventional title searching appears to be dependent on the number of works contained on the recording. Keyword retrieval is not as successful as title searching when title entries are provided. |
