I guess I'd better get with my nearly nonexistent tech skills. As I do with all my books, I first categorize then I alphabetize. However, if I have several books by a single author such as Eleanor Burns, Lynette Jenson, Debbie Mumm, I just alphabetize, since they have a distinctive style and I can usually find a project (even small ones) if i'm in the mood for a particular style or technique. Don't buy mags anymore unless I find a pattern I just have to have. I am also a page ripper and use page keepers to keep everything in 3 ring binders--just categorized, not alphabetized. I do have an old computerized catalog that I still add to and delete from, but it was first done before spreadsheets and barcode readers--Ah, something about older than dirt?
