Hi Kevin,
I've been trying to decide which of the first 2 books in that UML series to get (UML User Guide vs. UML Language Reference). Unfortuantely, since I leave in flannel land (read middle-of-nowhere), I cant find either one in a local bookstore to look at it.

So how about a recommendation of which one you would suggest for somebody with some basic UML under their belt (via UML Distilled book), who's only looking to purchase a single general purpose reference book? TIA!
