There is probably no New Englander more revered than Thoreau, and his Walden is still widely read today. We have the book in multiple formats including The Annotated Walden: Walden: or, Life in the Woods [818 THO].
Plan a visit to Walden Pond. It is less than an hour away, and worth the trip. For a photographic history of Walden Pond, borrow Thoreau's Walden by Tim Smith [974.44 SMI]; it is part of the popular "Images of America" series of books.
For a fictionalized look at Thoreau and his time in Concord, borrow Woodsburner: A Novel by John Pipkin [F PIP].
Woodsburner springs from a little-known event in the life of one of America's most iconic figures, Henry David Thoreau. On April 30, 1844, a year before he built his cabin on Walden Pond, Thoreau accidentally started a forest fire that destroyed three hundred acres of the Concord woods--an event that altered the landscape of American thought in a single day.
