Data analysis of the structure and use of library collections available in public libraries in Ljubljana between 1990 – 2000

The main goal of our research was to establish the extent to which recordings on magnetic tapes and optical discs were incorporated into library materials offered by public libraries, which are located in the area of the municipal community of Ljubljana.Using the statistical summary books, issued by public libraries, we gathered and analysed the accretion, stocks and borrowing figures of monographic publications,audio cassettes, compact discs, video cassettes and CD-ROMs. The findings show that monographic publications are still the fundamental material of public libraries. Among audio-visual media, video cassettes represent the most extensive collection, followed in number by compact discs, audio cassettes and finally CD-ROMs. The results of the analysis of borrowed library material are totally consistent with the above stated order.Quantitative measuring has also shown that the stocks of audio-visual materials do not reach the international standards for public libraries.
