Most online public domain versions of Shakespeare's texts are based on the Globe Edition of 1866, the Gutenberg Edition, or the MIT/Moby Edition (a revised version of the Globe Edition). There are many inconsistencies and errors in these editions so they are considered less-authoritative and poor for study. Alternatively, there are several quality editions of Shakespeare's works like the Riverside, Arden, and Bevington editions, which aren't free but come with a strong scholarly backing.The PlayShakespeare.com team used the First Folio of 1623 (and Quartos where applicable) and the Globe Edition of 1866 as sources for the texts on this site. We've re-edited and updated these versions to reflect the editorial standards of the PlayShakespeare.com scholarly team, therefore you can rely on the quality and interpretive accuracy of the PlayShakespeare.com texts.
