Just posted a comment to dale_in_queen's recent post, then realized that this might be of interest to the whole group:
I help to run a new cataloging site called
Squirl which is like LibraryThing, but for all of your other stuff. You can use Squirl to catalog your books, but you can also use it for music, movies, video games, or anything else you might collect. You can import things from Amazon or upload your own pictures for things that you can't find on Amazon (your old LPs, coins, action figures...). For example, here's my collection of my favorite
CDs.
Like LibraryThing, Squirl is free for up to 200 items and only $10/year for up to 5000 items.
Hope you check it out! And feel free to let me know what you think.
