I also started adding tags to the titles. It takes a little time but in the long run I think it could be useful.
Another really neat thing about LT is that if you click on the title of the work it takes you to a page which shows similar items (based, I assume on tagging) and if you click on the cover picture it takes you to Amazon.com. That's useful for us because we've been adding a link to Amazon for every book we have in our library and this just gives us a slightly easier way to find the record for a particular book.
