Abstract

Used on its own, Boolean searching will only find between 20-25% of the relevant information. However, Personal Librarian has search tools which offer smart searching techniques, in particular a relevance ranking function. Although the software does not offer full natural language searching, it provides a natural language perspective. Although designed originally for the creation of inhouse databases, Personal Librarian is now used for a range of other applications including electronic publishing on CD-ROM distribution. Personal Librarian may be built on UNIX, DOS or Windows and may be searched on any other platform
