First published in 1952, and originally delivered as the Sandars Lectures in Bibliography for 1950, this book examines the history of Jonathan Swift's Gulliver's Travels and the various changes made to it after its initial publication in 1726, when it was altered by a London bookseller without Swift's authorization. Williams traces the development of the text through its several editions, seeking the one that reflects Swift's thought most authentically. This book will be of value to anyone with an interest in bibliography or in the work of Swift.
