DMCA Designated Agent Directory"In order to qualify for safe harbor protection [under the DMCA], certain kinds of service providers—for example, those that allow users to post or store material on their systems, and search engines, directories, and other information location tools— must designate an agent to receive notifications of claimed copyright infringement. To designate an agent, a service provider must do two things: (1) make certain contact information for the agent available to the public on its website; and (2) provide the same information to the Copyright Office, which maintains a centralized online directory of designated agent contact information for public use. The service provider must also ensure that this information is up to date."
