Insight for the Blind has been producing Talking Books for the Library of Congress since 1975. Here is a short video with an interesting history of the different recording devices used to provide the blind and visually impaired with reading material going back to 1933!
In memorial and honor of Chris Guthrie (1969-2011) we at the North Carolina Library for the Blind and Physically Handicapped present a history NLS talking book technology told in his own words. We couldn't describe things any better so we let the best do it for us. We miss you Chris.
