1103.4 (E) Manufacturer, Publisher, Producer, Packager, or Creator of the Unit of Publication
As discussed in Section 1103.2, a unit of publication cannot be created merely for the purpose of registration. Instead, the works must have been packaged and distributed to the public as a single, integrated unit. An applicant may register the component works contained within a unit of publication, provided that the claimant manufactured, produced, published, packaged, or otherwise created the single, integrated unit. In other words, the unit of publication option may be used only if the claimant packaged or bundled the unit as a whole, or caused the unit to be packaged or bundled together.
When completing the online application, the applicant should provide a brief statement in the Note to Copyright Office field indicating that the claimant is the manufacturer, producer, publisher, packager, or other creator of the unit as a whole. When completing a paper application, the applicant may provide this information in a cover letter.
