How about trying this one for a start? Latin Jazz - The Perfect Combination by Raúl Fernández Chronicle Books, San Franciasco 2002 (ISBN 0-8118-3608-8) It does cover more recent latin jazz artists too but has a heavy emphasis on the 30s, 40s and 50s - and splendid photos and background info! I found my copy in the sale bin of an art bookseller over here in Germany so it should be available Stateside too. Good luck tracking it down!
