I have several books on the same subject and store them on shelves: Fat Quarters; Paper Piecing; Bargellos; Gees Bend; Quilt in a Day Books; Classic Instruction Books (Quilts, Quilts, Quilts; McCalls; Better Homes & Gardens). Others are shelved in no particular order. I don't accumulate magazines, when I do buy them, I tear out the patterns I like and put them in a 3-ring binder and dispose of the mags.
