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.
EIMA is an historical archive of major trade and consumer magazines in film, television, music, radio, and theater, from their inception to 2000. Includes weekly Variety, Hollywood Reporter, American Cinematographer, Back Stage, Billboard, Broadcasting, Picturegoer, Screen International, Spin, and more. UCLA has access to parts I, II and III of this database.
