United States Copyright Office in the context of "Barbara Ringer"

The Library of Congress (LC or sometimes LOC) is a research library in Washington, D.C., serving as the library and research service for the United States Congress and the de facto national library of the United States. It also administers copyright law through the United States Copyright Office, and it houses the Congressional Research Service.

Founded in 1800, the Library of Congress is the oldest federal cultural institution in the United States. It is housed in three buildings on Capitol Hill, adjacent to the United States Capitol, along with the National Audio-Visual Conservation Center in Culpeper, Virginia, and additional storage facilities at Fort George G. Meade and Cabin Branch in Hyattsville, Maryland. The library's functions are overseen by the librarian of Congress, and its buildings are maintained by the architect of the Capitol. The LC is one of the largest libraries in the world, containing approximately 173 million items and employing over 3,000 staff. Its collections are "universal, not limited by subject, format, or national boundary, and include research materials from all parts of the world and in more than 470 languages".

The James Madison Memorial Building is one of three United States Capitol Complex buildings that house the Library of Congress. The building was constructed from 1971 to 1976, and serves as the official memorial to United States Founding Father and president James Madison. It is located between First and Second Streets SE on Independence Avenue, across from the main library Thomas Jefferson Building, in Washington, D.C. In addition to various book and multimedia collections, it houses the United States Copyright Office, which is under the administration of the Librarian of Congress.

In legal discourse, an author is the creator of an original work that has been published, whether that work exists in written, graphic, visual, or recorded form. The act of creating such a work is called authorship, which means a sculptor, painter, or composer is considered the author of their respective sculptures, paintings, or musical compositions. Although in common usage, the term "author" is often associated specifically with the writer of a book, article, play, or other written work. In cases involving a work for hire, the employer or commissioning party is legally considered the author of the work, even if it was created by someone else.

Typically, the first owner of a copyright is the creator of the copyrighted work, i.e., the author. If more than one person created the work, then joint authorship has taken place. Copyright law differs around the world. The United States Copyright Office, for example, defines copyright as "a form of protection provided by the laws of the United States (title 17, U.S. Code) to authors of 'original works of authorship.'"

United States copyright registrations, renewals, and other catalog entries since 1978 are published online at the United States Copyright Office website. 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.

The Register of Copyrights is the director of the United States Copyright Office within the Library of Congress, as provided by 17 U.S.C. § 701. The Office has been headed by a Register since 1897. The Register is appointed by, and responsible to, the Librarian of Congress, with the Register's office located in the Library's James Madison Memorial Building.

Although the title suggests a clerical role, Registers of Copyrights have been responsible for creating the procedures and practices of the Copyright Office and establishing standards for registration of copyright. They have increasingly been responsible for setting or influencing United States copyright policy. Today the Register is responsible for administering rulemaking procedures and producing authoritative interpretations of some aspects of U.S. copyright law, as well as advising the Librarian of Congress on the triennial proceeding on exceptions to the anticircumvention rules of the Digital Millennium Copyright Act. The Register also routinely testifies before Congress on copyright policy matters.

In 1995, she was appointed to be the first associate register for policy and international affairs at the Copyright Office and was the copyright consultant for the Clinton administration's advisory council on the National Information Infrastructure from 1994–5.
