Boolean searching provides only records that meet exactly the conditions of the search, whereas relevance searching provides those records plus others that meet most of the defined conditions. Instead of numeric ranking, Voyager shows search results with a histograph that clearly shows how relevant each record is to a search. WebCat, one of the included modules, integrates a school library's online catalog and the World Wide Web, allowing in-library OPAC workstations to support Web browsers such as Netscape or Mosaic for catalog searching. To help save paper, it allows reports to be saved to disk or viewed on screen rather than printing them out. An expanded, 65-character Title field, and Publisher and Copyright fields have been added to the Book Database.
MARC records can now be importedeasily with an optional interface module.
Searching has become much more powerful, with variable field lengths, user-definable field names, and multiple database capability. Most LASs mentioned in this article integrate some form of media tracking or inventory control, but there are also products that are specifically designed with these duties in mind, such as Media Trak 3 from Niche Solutions, and Item Inventory and Tracking from Right On Programs. These programs suit institutions that desire only inventory control or already have a LAS that doesn't include those capabilities. One trend that is saving staff a lot of data entry time is the availability of programs that help convert, create and edit OPACs and MARC records. As evidenced in this article, the proliferation of Internet and Web access offered to libraries opens up many new possibilities in research and referencing.
