Unity is certainly getting more and more popular, and with the (limited time) release of Unity iOS and Android for free, the number of people interested in Unity is sure to rise. Along with the increase in popularity of Unity, there has been an influx of Unity books.
Therefore I put together this post to compile all of the books and their primary details into a single page. This makes picking out which book to buy/read as easy as possible.
Hope you find it useful. I am trying to keep this post as comprehensive as possible, so if I missed a book or made a mistake, please let me know!
