To help you get started, some examples are given here: If you are registering a website that contains some photographs, select Website and Online Works. For a sound recording, if you are also seeking registration for the underlying lyrics, music composition, arrangement, etc., select Sound Recordings. The information you enter will be used to prepare your application in accordance with the U.S. Copyright Office deposit requirements. The Title you enter will appear on the official Copyright Office Registration to identify the work, and thus, the title should be an identifying phrase.
Leave blank if there is no title. If you are registering a website, list the url (www.example.com) – Whatever you enter here will appear on your official Copyright Office Registration to identify the work. If this is a collection of works in a single application, such as a single album with several songs or a single collection of a number of essays, you must provide a title for the collection and you may provide titles to the individual parts, too, but you do not have to.
This means has the work been distributed to the public through sale, lease or lending? If you merely provide copies of an article, display art work or photographs or publicly perform something, it has not been published. If you mark your work has been published you may have to provide a deposit with the Library Of Congress.
