The Treasury of the Encyclopaedia Britannica

I found my copy of this gem in a thrift store book section and purchased it for an entire fifty-cents. So far this book has proven to be a intellectual powerhouse and it never disappoints. Articles have been hand picked by the Britannica editors from the best of the encyclopedias' authors over the years. Toward the back there are abbreviated treatises on various topics from some well knowns. Einstein on Relativity, Whitehead on Mathematics, and T.E. Lawrence on Guerrilla Warfare to name but a few. If you're a generalist and/or a fan of the encyclopedic style you need this book.
