For you bibliophiles out there, just got in a new book by John Train entitled, "The Orange: Golden Joy" that was released last year; Hardbound, 111 pages, color photographs. I've only thumbed through it so far, but my take so far -- not big enough to be called a coffeetable book, in my mind, but its value is more in the pictures, historical tidbits and various recipes, rather than as a "how to" book on growing citrus. Has a list of varieties, but these are very brief, so again buy it for the pictures, not for anything practical -- otherwise not bad.
