CD-MARC bibliographic databases as an alternative to other information sources: cataloguers' evaluation of the use of LC CD-MARC at Kenneth Dike Library, University of Ibadan, Nigeria

The Library of Congress (LC) compact disc machine-readable catalogue (CD-MARC) was recently acquired by the Kenneth Dike Library, University of Ibadan. Its use by the cataloguing librarians was evaluated in terms of efficiency (effect on cataloguing lime) and effectiveness (effect on monthly output) when compared with using other information sources such as microfiches, cataloguing-in-publication (CIP) data and printed sources - LC subject headings, LC National Union Catalogue, LC monographic series, etc. The positive influence of the new technology was evident as there were reductions in cataloguing time and increases in monthly output of items catalogued.
