Abstract

Describes the components and uses of computerized library information systems. Examines the rules stipulated by S.R. Ranganathan in his Classified Catalogue Code (ed.5) (CCC5) for the construction of catalogues and preparation of bibliographies from the point of view of their relevance and suitability for creating bibliographic databases. Compares rules of CCC5 with those of AACR2 and suggests modification of existing rules as well as incorporation of new rules. Concludes that in developing online catalogues or online bibliographic databases, it is neither essential nor desirable to follow strictly the rules of specific traditional catalogue codes such as AACR2 or CCC5. Describes a design for a prototype integrated database for a library system with the aid of CDS/ISIS software

Abstract

Standards are important for quality and interoperability in any system. Bibliographic record creation standards such as MARC 21 (Machine Readable Catalogue), CCF (Common Communication Format), UNIMARC (Universal MARC) and their local variations, are in practice all across the library community. ILMS (Integrated Library Management Systems) are using these standards for the design of databases and the creation of bibliographic records. Their use is important for uniformity of the system and bibliographic data, but there are problems when a library wants to switch over from one system to another using different standards. This paper discusses migration from one record standard to another, mapping of data and related issues. Data exported from CDS/ISIS CCF based records to KOHA MARC 21 based records are discussed as a case study. This methodology, with few modifications, can be applied for migration of data in other bibliographicformats too. Freeware tools can be utilized for migration.
