Cataloging sources. What cataloging sources do you use most? Any particular reason? Any idiosyncratic choices, or foreign sources, or sources you like better than others? Are you able to find most things through LT's almost 700 sources?
I use Amazon the most -- 385 of my currently 424 books were cataloged from Amazon. Amazon.co.uk comes in second with 19 (I think these are mostly my Doctor Who tie-in novels) followed by the Library of Congress with 12. I've never been unable to find something with LT's cataloging sources, so hats off to Tim and Abby.
