United States copyright registrations, renewals, and other catalog entries since 1978 are published online at the United States Copyright Office website.[1] Entries prior to 1978 are not published in the online catalog. Copyright registrations and renewals after 1890 were formerly published in semi-annual softcover catalogs called The Catalog of Copyright Entries (CCE) or Copyright Catalog, or were published in microfiche.[2][3]
