Goodreads is a library on your computer to keep track of books you have read, books you want to read and also books you are currently reading. You can search by author or book title for any book you desire. You can't actually read the books on this tool, but it's nice to have a list of books you want to read so you don't forget. You can search authors and see their profile and see all the books they have published. You can also have friends and see what books they are interested. I think it's very convenient for frequent readers.
I give Goodreads a 5 out 5.
