The article by Stephanie Steinberg provides some interesting statistics:
"About 7 million books are downloaded by Internet Archive users around the world each month, Kahle Brewster [founder of The Internet Archive] says. With 20 scanning centers in the USA and eight in countries around the world, the archive scans more than 1,000 books a day from more than 150 libraries, including the Library of Congress— the largest library in the world that also offers online digitalized collections of books, articles and newspapers."The article in USA Today does not mention genealogy. Instead, it focuses on providing books to the blind as well as to those with learning disabilities.
