Abstract
This paper describes the University of Botswana Library (UBL) retrospective conversion project and introduces the UBL automation planning activities. The paper also briefly discusses sources of records used in the creation of UBL database; authority control measures; decisions made regarding the editing of records and the recommended conversion procedures. More attention is placed on the actual UBL conversion project as well as the experiences of other libraries. This part details how the project was carried out at U.B. Library from September 1995 until July 1997 and reports implications in terms of staffing arrangements, success rates and quality considerations. Lastly, the paper describes the methods the library used to convert the collection. It examines the problems encountered throughout the project and gives advice to libraries that might be in the process of embarking on a similar project.
