Hanging Victorian Lamps of the Nineteenth Century (2007, Hardcover, Illustrated)

The photos and the company information presented in this book are top notch. Just remember it is price 'guide' not a price list/retail catalog to be used as a holy grail :) Markets and tastes change, and I've seen lamps sell for much less than list here, as well as much more. It should at least give you a starting point to determine the rarity and quality of different pieces. Even if you do no more than use it as a reference for manufacturers, what parts are needed to assemble the lamps, how they'd look put together, or as a coffee table book for the beautiful pictures, you'll no doubt get your money's worth however you look at it.
