Subject : Content protection (DRM) software now available
NLS has developed software that can be used to add content protection to locally
produced digital talking books (DBs) and magazines in order to bring them into compli
ance with copyright law for distribution to eligible individuals.
The software follows the DAISY Protected Digital Talking Book Standard, version 2,
and can be used to protect audio-only DBs compliant with the ANSI/NISO Z39.86-2002
standard (the same standard used by NLS for the production of digital talking books
and magazines). When used with the included public key, protected materials can be
played only on NLS digital talking-book players and authorized third-party players.
The software is available on the Network Library Services web site at
From the library menu, choose "selected reports and documents." In the "software
distribution" section, choose Digital Talking Book Content Protection (DRM) software.
The DRM software's summary page, which includes a download link, will display.
The downloaded ZIP file includes a file called "readme.txt" that provides instructions for
installation and use.
