Newspapers are one of the most prominent sources for performance reviews. For access to newspapers online, visit the Library's guide to News sources.
Databases used for finding scholarly criticism and popular articles also often contain reviews of plays and performances. Below are some of the key databases with review content. Some of them also allow you to pre-limit to reviews as a publication type.
Despite the amount of review content now available online, many earlier reviews can still be accessed with print indexes and reprint series. See the UCLA Catalog for the full record and any additional campus copies.
