Online (Electronic) Encyclopedias

Check this guide to find encyclopedias that are online. Some are general encyclopedias; some are specialized, focused on specific subject areas.


This guide contains several tabs with links to online encyclopedias of all kinds. Some are available only to Iowa State University students; others are free on the Internet. Most general encyclopedias are used to give a general overview on a subject or to help focus on a particular aspect of that topic. More specialized encyclopedias, such as The Encyclopedia of Education are scholarly and can be used as valuable research resources.
