I just purchased "The DAM Book" from amazon written by Peter Krogh and I have to say, I recommend it to everyone who shoots digital. DAM stands for Digital Asset Management. The book gives a detailed description on how to organize and cataloge your photographs in such a way that they will be easy to search through and backup. I recieved it today and I'm currently at page 82. So far it's a great book and I've already learnt loads of things I never took into concideration. The books website is http://www.thedambook.com/ where you can find a sample chapter and a very active forum. You can also find a pdf of chapter 2 if you search for the dam book on google. Strangely enough I think it was on microsofts website.
