AILWEB is a searchable database of descriptions of available resources on the World WIde Web. It is based upon the principal that the people responsible for a site are in the best position to describe its contents accurately. Site maintainers fill out a standardized form describing their site, and ALIWEB retrieves these documents hourly to refine its database. Users may then search by keyword, and have access to up-to-date information. Site maintainers may also add their servers to the ALIWEB database.
