1909.3 Publishing Separate Parts or Installments of a Work
When various parts or installments of a work are published separately, each part or installment is considered a separate work. As a general rule, an applicant should prepare a separate application, filing fee, and deposit for each part or installment of a work if those parts or installments were published separately. If the various parts or installments were published on different dates, the applicant should provide a separate date of publication for each part or installment.
NOTE: To avoid the need for filing multiple applications, applicants are encouraged to register an unpublished work as a whole before the various parts or installments of that work are published.
For a general discussion of the practices and procedures for registering multiple versions of the same work, see Chapter 500, Section 512.
