A catalogue raisonné (RAY-zon-ay), for those of you who might not know the term, is a book that shows the full range of an artist's work in sequence. Technically, a true catalogue raisonné has to meet a number of scholarly conditions regarding completeness, with notes on condition, provenance, and location of the works, among other things, and it needs to address any questions of attribution. Because not all of this pertains to a mechanical printmaking medium like photography, the term is perhaps not strictly applicable.
Still, the splendid new Ansel Adams: 400 Photographs published by Little, Brown is the closest thing we've gotten yet to a catalogue raisonné for Adams. It might not cover every negative he ever made, but it certainly contains all of his major work, divided into five periods beginning in 1916 and continuing through the 1960s. There are things here even I didn't know, and I thought I'd seen everything.
It's not a large-scale book (and not expensive, either—a mere $26.40 if you buy it through the link, making it very good value for money until the price goes up), but the pictures are large enough to enjoy. The reproduction, consistently very fine although not quite matching the best, will not stand in the way of anyone's enjoyment either.
Useful as an introduction to Adams for those who don't know his work very well, or as a handy single-volume survey of all of his work in chronological periods for those who are diehard fans. For anyone with a general interest in great photography: warmly recommended. For lovers of landscape and nature photography or fans of large format: essential. For Christmas and Hanukkah: you could do a lot worse!
