I love librarything.com!!!  It is a great tool.  I like being able to read reviews about books before I read them.  I can see uses for personal and professional.  I have already e-mailed my librarian the link to this site.  I can see having a book club with the teachers at school so we can discuss and read books but by the website, not in person.  It’s great!  I have added 13 books (very quickly I might add) and loved how easy it was.  It’s great!!   Thanks for this site.  It will make a big difference in my life.
