Query: Splendid writing, painstaking research!

As the editor of a forthcoming book of essays on John Burroughs, I have found The World of John Burroughs an invaluable resource. Its author is an in-the-field naturalist as well as a superb writer and scholar. The beautiful format of The World of John Burroughs might mislead readers to look at the pictures and ignore Edward Kanze's superb writing and painstaking research; but the book is filled with factual and verbal treasure-- including the most recent and complete research on the fascinating story behind the birth of Julian Burroughs. Most of all, this book helps to renew our awareness of the continuing relevance and liveliness of John Burroughs's contribution to American nature writing.
