Richard Rhodes, author most recently of the excellent biography John James Audubon: The Making of an American, has edited another very useful Audubon volume, the Everyman's Library Audubon Reader. A collection of personal letters, autobiographical writings, and chosen segments of Audubon's extensive ornithological species accounts, this volume offers an open window into the writings of one of America's greatest naturalists through his own words. Rhodes has edited wisely, drawing from a wide range of materials covering the entire scope of Audubon's life and works.
For any Audubon enthusiast or nature-writing fans in general, this book will happily fill a gap on your shelf. Whether read straight through or dabbled at will, I recommend Rhodes' effort highly.
