The Rosetta Project’s collections currently contain about 2,000 antique children’s books which were published in the 19th and early 20th century. They are currently available for free and can be read online or downloaded and saved for future readings offline. Translations into multiple languages are also available for many of the books.
Donations of old books, or financial aid for the non-profit group is welcomed. More details are available at their site. The Rosetta Project
