Nationalbibliografin: en komparativ studie över musikområdet i Norges, Sveriges och Danmarks nationalbibliografier.

Sammanfattning: The national bibliography is an important tool in information retrieval. Bibliographies as lists of books have existed for centuries, but the national bibliography as we refer to it today, as a directory of the total national imprint, has only existed for about 50 years. The object of this thesis is to investigate music documents in Scandinavian national bibliographies. The method I have used for this investigation is a comparative study of the music departments in the national bibliographies in Norway, Sweden and Denmark. The investigation is performed by answering the following questions: How do Norway, Sweden and Denmark live up to IFLAs Guidelines and recommendations for the national bibliography? Can one discern any differences between the three countries in this area? The documents in focus are sheet music and phonograms. The material for the investigation has been collected through studies of literature, from the web sites of the national bibliographic agencies and through complementary interviews with librarians at the three national libraries. The study is based on IFLAs definition and some of their Guidelines for the National Bibliographic Agency and the National Bibliography from 1979 and their complementary recommendations from 1998. The investigation has shown that there are only minor differences between the music departments in national bibliographies in Scandinavia, and that they all follow IFLAs recommendations in a satisfying manner. The major aspects, like selection criterias match well in all countries, while the differences are found in the information to the national bibliographies on the web.
