You will receive one or two Talking Book Topics (TBT) catalogs when you begin service. Six to eight weeks later, you should receive a new issue of TBT. This catalog is issued every two months and lists the newest books available on digital book cartridges. Catalogs are available in large print, digital book, HTML, or accessible PDF formats. Braille Book Review lists braille books and magazines recently added to the NLS collection and available through a network of cooperating libraries. NLS publishes Braille Book Review bimonthly in braille, large print and HTML. Contact Kansas Talking Books to subscribe to this publication.
