Here are links to the resources I discussed in your ACS research class for The Tempest critical edition mid-term project. In addition to these resources you may also consider taking a look at the Cambridge Companion to Shakespeare (in our catalog) as well as both the Royal Shakespeare Company and Globe Theater webpages for information and media regarding performances, marketing, etc.
