Library E-thing

This "thing" they put together online is really powerfull, works so quickly and it is very friendly to use. They say they care about books, not selling them... excelent! well, they give a good hand to Amazon to sell books though.
I like the fact you can read others review, and what other good books you are still missing on your shelf.
The social aspect of this site is massive, there are so many groups and different topics! as What You're Reading, Books being turned into movies (very useful when a patron comes to you asking for the book of "that"movie, Share a line or short passage from your current book, etc, etc, etc, and not only books, but also art in general, culture, and many more.
Enjoyable.
