As said before, the Portfolio series from Lodima will give you the best rendering of Brett's prints.
If you are new to Brett or just want a very comprehensive survey of his work, then the book/catalog "Brett Weston: Out of the Shadow" is excellent.
There have also been a couple of recent books on his life: "Brett Weston: a Restless Eye" by John Charles Woods, and "My Time with Brett" by Randy Efros. I especially liked the latter.
