Abstract
The Science Library Catalog is a direct manipulation browsing oriented online catalogue intended for use by children. The catalogue provides an innovative interface tailored to the cognitive development of children, yet can be implemented by loading MARC records from extant library collections. Reprots on the implementation of keyword clustering algorithms used to extend the DDC class number assignments on a database of over 8.200 bibliographic records
