Dd is studying this for GCSE. Which edition should I buy her? Not for passnotes, etc, but there are editions which include other plays, or an intro by someone scholarly, or just a straight script. Also, reviews on Amazon suggest that some lines in some editions are different to other editions - how do I know which is the correct version?
(I have asked dd to get this info from her teacher, or just take a pic of the ISBN on the school's copy, but she's in prickly teen melodrama mode ATM.)
