Book confession time: I have around 400 books...which is only a problem (to me) when I travel. I collect Europa and NYRB editions as well as classic Modern Library. And I‘m trying to trade out paperbacks for hardbacks as I find them. So today I finally forked over the 4.99 for this app and I‘m loving it. I‘ve got 73 catalogued so far. I can create categories, apply descriptive tags, and scan barcodes...among other things. I highly recommend! ⬇️
