Note that many editions of Shakespeare modernize the language a bit. I don't know what Folger does (anyone know?) and I haven't found an authoritative source for the original, but Open Source Shakespeare is the best I've found so far:

Does anyone know an authoritative source for the 'original' text [0]? I suppose books in the Interet Archive might be a good place to look next.

[0] In some cases, the true original has been lost to time and the earliest text we have was published many years later.
