The WWW Virtual Library 
http://www.w3.org/hypertext/DataSources/bySubject/Overview.html 
Less hierarchical than Yahoo, this is a listing of topics with cross-references. The Library is distributed, with sections on different subjects maintained by different people all over the world. The pages given differ from Yahoo’s for the same topics. 

EINet Galaxy 
http://www.einet.net/ 
Another hierarchical subject directory. Contains different categories from either Yahoo or the Virtual Library; a good complement to Yahoo, it bills itself as being for “professionals.” 

World List of W3 Servers 
http://vlib.stanford.edu/Servers.html 
A geographic directory of WWW servers arranged hierarchically by continent, region, country, and state or territory, with clickable maps for some areas. 

Virtual Software Library Front Desk  
http://castor.acs.oakland.edu/cgi-bin/vsl-front 
Publicly available software. Speed is good, but the search screen is confusing; think carefully when filling it out. 

DejaNews Research Service 
http://www.dejanews.com/ 
An index to archived articles from Usenet newsgroups. You can search all newsgroups or create a filter to limit your search by newsgroup, date, or author. See also Infoseek , Alta Vista , and Excite Netsearch for simpler newsgroup searches. 

Library of Congress Catalog 
http://lcweb.loc.gov/z3950/gateway.html 
A forms-based way to search the Library of Congress book catalog. Rather unwieldy and difficult to use—make sure to limit your search as much as possible, since only 10 or 15 records can be retrieved at a time. Helpful for finding out-of-print books that the Amazon.com catalog won’t have. 

webCATS - Library Catalogues on the World Wide Web 
http://www.lights.com/webcats/ 
Listings of every on-line library catalog with a World Wide Web interface, organized by geographic location, library automation vendor, and library type.

The Internet Movie Database 
http://www.moviedatabase.com/ 
A freely-searchable database of movie information compiled and continually enlarged on the Internet.

Amazon.com Books
