GALILEO is a collection of over 200 electronic databases that index thousands of periodicals and scholarly journals. Full text is available for many of the articles, although full text will not be available for every article you find.
You can start your search from the GALILEO link or Find an article on the Library’s webpage. If you use the search box on the opening GALILEO page, you will be searching all of GALILEO's databases at once, plus some extra materials (like Library ebooks).
If you want a more focused search, you can choose a specific database from GALILEO's Databases A to Z link.
Not sure which specific database to choose? Try the Library's Subject Guides. Each Guide has subject-specific article databases under the "Find Articles" tab.
