Q. What types of books will be available?
Most of the titles now available are late 19th century works. There are books in more than 200 languages from Acoli to Zulu, although most are in English, French and German. That will continue to grow and change as the digitization effort continues. Among the interesting titles now available include many that have already been purchased as reprints through a much smaller-scale existing program.
So nothing exciting exactly, but curious.
