The company said that users will be able to choose from a diverse collection of public domain titles, from well known classics to obscure gems.
"Before the rise of the public library access to large collections of books was the privilege of a wealthy minority," Google said.
"Now, with the help of our wonderful library partners, we are able to offer you the ability to download and read PDF versions of out-of-copyright books from some of the world's greatest collections."
Titles including Aesop's Fables, Shakespeare's Hamlet and Dante's Inferno are available for free.
The books can be accessed at Google Book Search by selecting 'Full view' when performing a search. Copyrighted books are not available for download.
