The copyright office is looking for specific types of information
(e.g., DVDs).  They should have these characteristics:
* The information is covered by copyright.
* There is some sort of access control on the information (e.g., DVD
  region encoding).
* There are some uses of this information which are explicitly
  permitted by copyright law (e.g., fair use).
* The access control prevents this type of use (e.g., DVD region
  encoding on a DVD you bought in a different region).
* Getting around this access control is prohibited (e.g., deCSS is

To put it more simply (I hope): the copyright office is looking for
cases in which people have been denied their fair use rights due to
access control, and they are prohibited from circumventing that access
control due to laws like DMCA.
