How can I prevent personal information from being placed on the Copyright Office’s website?

“All information provided on the application for registration will become a permanent part of the public record of the Copyright Office, and some of that information will be available online through the Office’s website, including the name and address of the copyright claimant. Any information provided in the rights and permissions section of the application will also be made available online, but providing rights and permissions information is optional. Applicants who want to include rights and permissions information but do not want to provide personal details can use third-party agents, post office boxes, or designated email accounts. If someone else submits an application on your behalf, it is still your responsibility to ensure that information that you want to keep out of the public record is omitted. In certain cases, it may be permissible to register a claim in a work either anonymously or pseudonymously (under a fictitious name). Other categories of information in copyright applications that may be made available online include the following: type of work, registration number, title of the work, author, authorship, preexisting material date of creation, date of publication.”
