There are lots of books, magazines, websites, articles, etc. that give a vast array of useful techniques for doing things in Photoshop. I've bought the books, saved the magazines, and bookmarked the websites. But when I have a specific Photoshop problem or want to do a specific thing, I have a terrible time finding the exact page in the book, issue of the magazine, or website that tells me how to do it. Has anyone come up with a good way of indexing all of this information so that one can find what one needs in a reasonably short time?
