A discussion of the variability of how Hamlet can be played, focusing on several recent (ie 2002) productions in New York City. I figure this article could be used if one were wanting to compare and contrast ultra-modern stagings of Hamlet with others from the past.

An article that appears to catalougue and describe some of the textual sources Shakespeare used when writing Hamlet (and Romeo and Juliet.) The library wouldn't let me access it from an off-campus computer though!
