If you're a fan of Shakespeare, you're going to love the University of Pennsylvania Library's online Furness Image Collection. Composed of books, manuscripts, artifacts, and over 2,000 prints and photographs, this archive of material is not just about Shakespeare's works, but also about the history of Shakespearean theatrical presentations. The theatrical performers and performances of such works are documented via the images in the online collection, most of which date from the 19th century. On the homepage you can choose do a simple or Boolean Search. You can also sort results by title, year, play or several other options.
