"Cramer's notes are immensely useful. His edition of Walden will be a boon to ordinary readers and scholars alike." Dennis Donoghue, author of Speaking of Beauty; "There is nothing like this - within the covers of one book - in the world of Thoreau scholarship. It amounts to a Thoreau encyclopedia in one volume!" Joel Porte, author of Consciousness and Culture: Emerson and Thoreau Reviewed"
