A database is a collection of abstracts, indexes, full text documents (ebooks, articles, statistics, conference papers), or digital media (images, video, audio, maps). Content is created and managed by publishers and / or indexing services, and searching is hosted by their own licensed platform or database vendors like Ebsco and ProQuest.
While some databases are broad and multi-disciplinary in scope, most specialize in a given subject area. Click the Databases tab on the Library homepage and choose from the "Select a Subject" list for a shortlist of recommended databases, or use the A-Z listing if you have a specific database in mind.
Discover is an option that allows you to search across all physical / electronic library materials and most databases all at once.
Here are a few good choices to begin finding articles, reviews, and criticism. Some also include scripts and performance videos.
