With just a "little" prompting my wife has given me a new book on trikes for my birthday. I am a new trike owner, and as always anything I get into I will read almost anything and everything I can get my hands on about the subject.

The book is "Free on three". It is a little pricey ($40) for a paperback, but it is huge with 736 pages. It appears to have almost everything you would want to know about trikes. Not only does it have all the information written by the author, it has pieces by major bike store owners, and trike manufacturers. IMHO it is a really great book.
