This is a wonderful tool and goes a long way to scratch the "library itch" I've felt since the start of the pandemic. Projects like this make me very happy that I donated to IA this year, and I'd encourage anyone else who likes them to do the same.

One question: are there any plans to sort fiction by author, similar to what is done in real libraries? A lot of fiction is already available in this tool, filed under DDN 8xx, but the groupings are pretty broad.
