Do you use any of the online book-cataloguing sites, like LibraryThing or Shelfari? Why or why not? (Or... do you have absolutely no idea what I’m talking to?? (grin))
If not an online catalog, do you use any other method to catalog your book collection? Excel spreadsheets, index cards, a notebook, anything?
Yes, I use LibraryThing.
It really is a fun thing to do, "cataloging" your books (especially since you don't actually have to remember your MARC codes to do it). My LT library is definitely still a work in progress. I add new books as they come in, but I haven't been able to get the base collection completely entered yet.
Russell's started entering his books as well. He has his own LT library and gets a huge kick out of being the only person to own a particular book.
