Abstract

Faced with the need to undertake the retrospective conversion of the library catalogue, at the International Institute of Tropical Agriculture Library, Ibadan, Nigeria, 2 possible approaches to conversion were indentified: use of a previously compiled accession list of materials available in the manual system; and scanning of all books and periodicals to create entries from source. Having chosen the first option, the next stage was to select the best way to proceed from several options. In the case of books and book chapters, the options were: use of MARC tapes; use of CD-ROM databases; downloading from online databases; and creation of original cataloguing and indexing entries. The first option was considered to cumbersome; the second was too expensive; the third was not viable with present telecommunications and INMARSAT satellite online access. In the case of periodical articles and conference proceedings, the options were: use of abstracting and indexing services on floppy discs; and locally generated indexing. The first option was not considered viable due to the scattering of entries over many CD-ROM databases; the second was rules out because of lack of coverage and problems in copying records in ASCII format
