If you're not sure where to start, you can enter keywords (production title, costume designer name, etc.) into LibrarySearch to search across a large selection of our magazines, newspapers, and trade publications. After you enter your search term, on the left hand filter bar, choose Resource Type > Articles, Newspaper Articles, etc.
If you're looking for something specific (like a review from an international publication or an article from an 1892 issue of the New York Times), or if you're not having much luck with the starter single search box, try searching within specific databases below.
Beyond the news resources above, you can also find critical essays and performance reviews in these broader research databases.
