I was having much the same problem: It said "yes, there's a Lost_in_Pages" but it wouldn't let me do anything with that information. Which I think might be why so many people were using Goodreads: It had a somewhat better user interface. (Also, I want to be able to say "the one from Project Gutenberg" to the edition question. Which, considering that they'll tell you if the book *is* on PG, you'd think LibraryThing would do.)
