The DH and I have finished cataloguing our books, or, rather, the ones that are on shelves or otherwise easily accessible. We still have four or so boxes of language books (mostly Latin) and children's literature that will get catalogued next time we can actually get to said boxes. Current tally is 1430 books, but there are a few multi-volume sets that we only entered as a single item, so our actual volume total is closer to 1445.
Go on, take a look . We still have to edit some entries and add tags, but you can get a good feel for what we own. It appears as though the DH owns ways more books than I do. I think that surprises me.
