1010.6 (H) Electronic Serials
As a general rule, the applicant does not need to satisfy the best edition requirement in order to register a website or to register a work that has been published solely online. However, there is a limited exception to this rule for electronic serials published in the United States on or after February 24, 2010. If the U.S. Copyright Office has determined that an electronic serial is subject to the mandatory deposit requirement, the applicant may need to submit two complete copies of the best edition in order to register that serial with the Office. For a definition of “electronic serial” and a discussion of the mandatory deposit requirements for such works, see Section 1010.7.
