We've read many plays wholly by Shakespeare and several plays partly by Shakespeare. This week, we're going to read a non-canonical play, i.e., a play whose Shakespearean authorship is questionable. Edward III is almost certainly not in your Complete Works, so head to the library or read it online here.
Yes, I know, we could probably get away with skipping it. But after working so hard on the Shakespeare in a Year project, you might look back years from now -- when perhaps this play will be part of the official canon -- and think, "Darn, we almost made it, except for Edward III." You don't want that, and neither do I. Consider it insurance.
(I will understand, however, if you can't get to it this week because you're too busy watching the royal wedding over and over again ... or shopping for hats.)
