The Invisible Web

A large number of content-rich databases from universities, libraries, associations, businesses and government agencies are almost invisible to average search engines such as Google, Lycos and Yahoo. One reason is because these search engines are not able to actually run the databases on these sites and often will simply overlook them. Sometimes these huge databases will make no attempt to advertise themselves (with meta tags, etc) and are never catalogued by the search engines.

ERIC
The Educational Resources Information Center (ERIC) database is the world's largest source of education information. The database contains more than 1,000,000 abstracts of documents and journal articles on education research and practice. The documents in the database can ordered from the ERIC Document Reproduction Service. Over 50,000 documents are now available on-line, on-demand. Journal articles can be ordered through various journal reprint services. ERIC is a federally-funded project of the U.S. Department of Education, Office of Educational Research and Improvement. http://www.eric.ed.gov/

ERIC Calendar of Education Related Conferences
The ERIC Calendar includes more than 700 international, national, regional, and state conferences scheduled for this year and next year. To provide contact information for sponsors who posted conferences in the past, the Calendar also includes last year's conference information. The Calendar database is updated throughout the year as new information becomes available.
