I have hundreds of cookbooks in my collection as well as my computer files. I started a recipe box with the name, book or file, page, and brief notes on an index card, filed alphabetically. Each time I try something new I add a card to the file. This way I know exactly where to find it next time!
I found this tip in a magazine, and was thrilled to find it was submitted by a woman who lives very close to me! It's a wonderful way to incorporate all my favs into an easy-find system, instead of paging thru endless books.
