A few years ago I started trying to keep up by adding books to my Goodreads account under an “owned” bookshelf. It’s a bit clunky to use that site but works decently enough for a rough cataloguing. This doesn’t have all of my multiple editions for certain things like James Bond novels and Hardy Boys collections.

…I can’t say no to cheap books…it’s a weakness of sorts…
Jefferson put it best: “I cannot live without books.”
