No one writes more knowledgeably or brilliantly about textual criticism than Tanselle. --Washington Post Textual criticism--the traditional term for the task of evaluating the authority of the words and punctuation of a text--is often considered an undertaking preliminary to literary criticism: many people believe that the job of textual critics is to provide reliable texts for literary critics to analyze. G. Thomas Tanselle argues, on the contrary, that the two activities cannot be separated. These short, lucid, well-written, humane lectures are essential reading for graduate and undergraduate students concerned with texts of any kind requiring critical attention--and for their teachers. --Review of English Studies G. Thomas Tanselle is Vice President of the John Simon Guggenheim Memorial Foundation and Adjunct Professor of English and Comparative Literature at Columbia University.
