Automating Acquisition through SOUL 3.0
Abstract: Library automation is an integral part of the development process of any library or resource center. Traditionally this includes automation of acquisition, serialization, cataloging and circulation. But most libraries do list entries of reading material and display them via OPAC. These libraries have been equally successful in computerized issues and returns. But the real difficulty lies in the automation of acquisition activities. It is forgotten that cataloging begins with acquisition. …
