I am sure you have heard of goodreads, but just in case you haven’t, let me tell you just a little about it. goodreads is an online manager of books you have read, want to read and are busy reading. While keeping track of this, you can organize your books according to categories you choose.
I have organized my books according to a whole variety of categories such as theology, language-studies, christian-thinking, baseball, bible, politics, heresy and many more!
It is very easy to use, and you can keep track of books as you read them by entering the page that you have just finished on the day. It will then show you how much of the book you have read percentage-wise. Once you finish books you can rate them, review them, and add them to a list of favourites.
Here is a blurb from the goodreads website:
“Goodreads is a free website for book lovers. Imagine it as a large library that you can wander through and see everyone's bookshelves, their reviews, and their ratings. You can also post your own reviews and catalog what you have read, are currently reading, and plan to read in the future. Don’t stop there – join a discussion group, start a book club, contact an author, and even post your own writing.”
