Presentation signed by author. Offprint of Studies in Bibliography. vol. 15, 1962. J.G. Cozzens published in both England and America, and used the 2nd "1st edition," usually but not always the English one, as a chance for minor rewriting. The author examines some differences between Cozzen's 1st American and English editions, and suggests that libraries and collectors wanting complete coverage of such authors must obtain all first editions.
