Have added some more links to the Shakespeare Sidebar. These include a shop (Shakespeares Den), the plays where they can be read online (Shakespeare Plays Online) and the famous Folger library.
I think the Shakespeare Resource Center http://www.bardweb.net/index.html looks to be the best source for everything Shakespeare - plays, authorship debate, biography, historical background etc. This site is already linked in the Sidebar under The Authorshop Debate
Cant stop to chat sorry - must get ready for the day job now.
