Description: ISBN10: 0195051610, ISBN13: 9780195051612, [publisher: Oxford University Press Inc, United States, New York] Softcover Covering 400 years of Shakespeare scholarship, Schoenbaum's now classic William Shakespeare: A Documentary Life received high acclaim from critics and scholars. The New York Review of Books called it "a masterpiece," and the Guardian labeled it "our best life of Shakespeare." Making the resources of the world's greatest Shakespeare collections more accessible to all readers, this updated "Compact Life" contains a refined and amplified version of the original text and fifty of the original documents reproduced in smaller format. Schoenbaum has incorporated new material into his narrative, including an eyewitness account, in harrowing detail, of a murder believed to have occurred in New Place, the house that Shakespeare bought in Stratford in 1597. He also provides a new postscript which includes newly-compiled information from recent research on Shakespeare. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged. [Goring-By-Sea, WS, United Kingdom] [Publication Year: 1987]
