The Library of Congress acquires collections through many means standard to cultural institutions, including donation, purchase, and bequest. But we also have one unique acquisition source: copyright deposit. In 1870, Congress passed an act centralizing copyright registration at the Library and requiring the deposit of two copies of each registered work. Not every deposited item becomes part of the Library’s research collections, but many do.
In a webinar next Wednesday, May 20 at 3:00pm Eastern Standard Time, Owen Ellis, a Prints & Photographs Division (P&P) archivist, and Sara Duke, the division’s curator of popular and applied graphic arts, will discuss P&P’s work selecting, processing, and making accessible printed ephemera that was acquired through copyright deposit. The webinar will discuss material deposited with the U.S. Copyright Office between 1909 and 1978.

Owen and Sara will focus on selections from Copyright Classes G, I, and KK, works that Owen says “document the creativity and commerce of the American people.”
In the pre-1978 classification system, Copyright Class G consisted of works of art created for personal and commercial use, including illustrations, comics, designs for greeting cards, and games, among others.

Reflecting on the importance of copyright deposits at the Library of Congress, Sara writes, “From books to posters, from manuscripts for plays to the typescript copy of the Rev. Dr. Martin Luther King’s ‘I have a dream’ speech given at the 1963 March on Washington for Jobs and Freedom, deposits have formed the basis of the collections of the Library of Congress.”
The items to be discussed in the webinar are the stuff of everyday life. “The commercial art prints are valuable for the insight they offer to the development of packaging, toys, computers, and medications,” continues Sara. There is so much to be learned from these objects about the history of technology, communications, popular culture, political context, and more.
