- Abstract
- WWW search engines are not comprehensive in their searches. They do not search: Adobe PDF file or other formatted files, registration files, and data sets. Basic search strategies can give access to some of the hidden content. 2 databases are also available to provide access to the hidden information. Excite's News Tracker searches a database of selected online publications. ATI databases from PLS, Inc. presents access to a variety of Internet accessible databases that may require membership or the payment of a registration fee
