The Merchant of Venice

From the publisher's website:

Each book includes an essay on the theatrical world of Shakespeare’s time, an introduction to the individual play, and a detailed note on the text used. Updated by general editors Stephen Orgel and A. R. Braunmuller, these easy-to-read editions incorporate over thirty years of Shakespeare scholarship undertaken since the original series, edited by Alfred Harbage, appeared between 1956 and 1967.
