I'm definitely not as 'techie' as lots of you are out there! I keep a printed list of books I already have, so I don't buy again. My books are alphabetically filed in the bookshelf, and magazines in separate sections according to the name, along with patterns. Plus, I have a recipe box with subsections for various categories: scrappy, king size, children, babies, primitive, applique, etc., and have referenced patterns, magazines and books with notations as to which section, date, pages, etc. When I need ideas, I do through the recipe box and find the cards for that category, and I know just where to go to review the information for quilts I may want to make.
