13. Access to Digital Materials
Digital Rights Management is about content control
Several ways to use digital materials:
personal use
typically purchased by individuals on a subscription or per-use basis.
professional use
typically acquired (for fee or legal agreement) by an organization or university on a bulk basis, with access redistributed freely to members of the organization.
public use
as a citizen, entitled to an information commons, and other basic information rights, such as Fair Use and Freedom of Information

14. Digital rights technologies
The different uses of on-line materials have different requirements
they will likely require different technologies.
Requirements vary about the needs and controls for privacy, the economic recovery model, the needs and controls for security, etc.
e.g. ability to snip fair use clips
Who is developing the digital rights technologies for professional and public use?
