I collect a lot of what I consider reference books...histories, stuff related to various time periods but that aren't really histories, like books on fashion and furniture, art, technology and other related things for the time period involved, and lots and lots of crafting and DIY books. I have a smaller collection of classical literature, books on language use, a bunch of books on maths, some geology, atlases,both regional and historical, books useful for teaching English composition (which I used to teach), a small assortment of books on physics, books on folklore, books on household management that are victorian reprints or earlier, and other books I just thought were cool. I do have some very old needlework books that were printed in the 1840s-1890s. Books on textile history, at least one with samples of the types of cloth mentioned, herblore, gardening, and various things useful to reenactors. I even have a facsimile edition of the first Encyclopedia Brittanica, and a pretty big collection of religious texts, largely catholic, but not entirely. And then there's my manga collection, but that's focused only on a few series.

The purpose of the catalog really wouldn't be for the titles. It would be so I could do key word searches. Sometimes I forget which fact came out of which book, especially in history texts that are collections of articles by different writers.

Not counting all the little crafting books, which tend to be slender, I suspect we're easily pushing at least 2000 volumes, not counting my collection of digital books. I'm kind of scared to count. After a while, it gets hard to remember which book what fact was in. The marc software libraries use really is designed to help cross reference better. I like it, having used it.

But don't know if I'll ever really get around to doing it.
