Google Books has converted numerous public-domain operates to this open format.
In 2010 e-books continued to achieve in their own underground markets. Many e-book publishers started distributing books that have been inside the public domain. Simultaneously, authors with books that had been not accepted by publishers provided their functions on the net so they could be observed by other folks.
