About 5 percent of texts have been digitized as of 2006.[3]
Older print books are being scanned and optical character recognition technologies applied by academic and public libraries, foundations, and private companies like Google.[4]
Unpublished text documents on paper which have some enduring historical or research value are being digitized by libraries and archives, though frequently at a much slower rate than for books (see digital libraries). In many cases, archives have replaced microfilming with digitization as a means of preserving and providing access to unique documents.
