BookHoard catalogs your library about as fast as you accumulate it: scan a barcode and the book's on your shelf in seconds, or photograph a whole bookshelf and add the lot at once. Then it does the things a list can't; flags duplicates before you rebuy, finds the volumes missing from your series, values the collection for insurance, and tells you how many of your books someone has tried to ban. No ads, no tracking, no feed. Your shelves were always your business.
