Last year, when I began putting together my library database, one of my goals was to distinguish between Volumes - physical books - and Works - individual, self-contained pieces of writing, which might appear in more than one Volume. I'm in the process of "subcataloging" my library, recording which Works appear in which Volumes. This is a rather more tangled task than I expected, and I'm going to mumble and grumble about it under the cut. Feel free not to look.
