There are tons of books on the subject. While most of them deal with professional lighting equipment, the techniques they teach can easily be modified for work lights or other consumer fixtures. Filmtools.com has a good collection of books for sale, as does theasc.com (found under "store") and cinematorgraphy.com (found in the "Students and First Time Filmmakers" subforum). Amazon.com will have every book ever written on the subject, but you'll have to sift through the bad and the ugly before you can find the good. If you are interested in a career in professional film and video production, then I would suggest staying away from the "low budget" and "guerrilla" filmmaking books. You'll learn a lot more skills that will have long-term usefulness from books geared towards professional production, rather than amateur production. However, if you're just making videos for your website or blog and want to know how to make them look nice, the low budget and guerrilla books will work just fine for the most part.
