What's the best thing about this virtual reference center? You don't need a library card to use it. To start, wander around the home page and familiarize yourself with what's there. Under "Reference Desk," check out the links to several topics, including maps, statistics, associations, and business information. Click on "Maps" and up pop links to sites that offer everything from driving directions to subway maps. Jump over to "Business Information" to call up sources for company profiles, stock market analysis, and much more. "Reading Room" provides access to newspapers, magazines, and academic journals. Finally, be sure to investigate the links under "Lists" on the home page. Our favorite list gives the 50-most-popular word searches on Lycos the previous week.
