Recently my brother invited me to sign up a well organized site-goodreads. This site is all about keeping account on what books you read. One can invite friends and when they update any information about the book an email will be sent to keep informed about their tastes. Here is a preview on what I read.
The preview is not showing the complete list. One can make number of shelves and arrange the books. A review can also be written about a book. No harm in spending time on this kind of sites.
