Librarything gets a 'five paw rating'

My Mum thinks that Librarything is just 'the cat's whiskers'. It will be a fabulous readers advisory tool for her. It has been fun creating a bookshelf for some of our recent reads, and adding tags to the books, but what she likes the most is being able to search other peoples' lists to find similar authors and subjects. Mum is also very excited about being able to create a shelf of things 'to read' that she won't lose easily. It has even allowed me to learn more about my Mum. She seems to have a preference for thrillers, crime fiction and stories about vampires. Should I be worried????
