The Web can be used for collaborative learning activities between teachers and students or students and other students. Much of the power of the Web is in its support for distributed work that can be shared through the medium of the Internet. Listservs and Web pages may be used to make available tables of contents, abstracts, and entire articles of electronic journals. Another powerful utility of the Web is the search engine. This utility uses keywords to search the Web and find material which contains those words.

It runs a search using multiple engines simultaneously. It currently employs twenty-four search engines and is considering the addition of five more.
