611.1 (A) Year of Completion for an Unpublished Work Created Over a Period of Time
If the work is unpublished and if the author created the work over an extended period of time, the applicant should provide the year of completion for the most recent iteration of the work. If the applicant provides a year of completion for each iteration of the work (e.g., a cover letter explaining that the author completed the first draft in 2006, the second draft in 2007, and the final draft in 2008), the registration specialist will replace that information with the year of completion for the most recent iteration, and will add an annotation to the registration record specifying the source of that information, such as: “Regarding year of completion: Corrected by Copyright Office from cover letter.”
