You pose a typical question in that you want the "best" book to look in. There are few "bests" in anything. There are sources and most have a degree of value, one way or the other. The better educated you are in your chosen field, the better you will be at determining the degree of value of any given source.
The Warlock book on De Kolta has its pluses and minuses. Warlock reproduces Goldstons nonsense on the double-ended bird cage apparently without doing any analysis of the method presented and its obvious impracticality.
One of the more interesting parts of the Warlock book is the publishing of a short memoir by de Koltas widow, Alice Mumford. In it she comments that the famous Vanishing Cage was sold to Kellar not by de Kolta himself, but by the cousin, behind de Koltas back. She also observes that de Kolta came backstage at Kellars show and saw a Cocoon. Kellar, seeing their surprise, said that hed bought it from Maskelyne when he was last in England. This strongly suggests that, as Ive written elsewhere, Kellar and Maskelyne had a business arrangement that stretched over many years and that Kellar was not a thief as has been put forward by others.
Most illusions require the use of a stage, curtains and lights for their proper presentation. This is why the most popular and often-seen illusions used by working magicians are the Sub Trunk/Canvas Covered Box, the Broom Suspension, the Lester Lake Guillotine, the Sword Basket, and the Zig Zag. All of these illusions can be presented in circumstances that most working pros find themselves...dance floors, small risers, and places without a proper stage. Few, if any of de Koltas illusions meet these practical criteria.
