I was Googling for G.K.Chesterton’s “The Man Who was Thursday” the other day and lo and behold, there it was, in all its glory, free – along with a Father Brown, The Napoleon of Notting Hill and a handful of others.
The place has thousands of free classics. Conan Doyle, Dostoyevsky, Edgar Rice Burroughs, you name it. I might break down and actually buy an e-reader one of these days.
The books are available in six different formats, ePub, Mobipocket/Kindle, PDF, Sony Reader, iLiad, Custom PDF.
