Alexander Magoun was the curator for the David Sarnoff Library from 1998 until 2000. After earning his Ph.D. in American History from the University of Maryland in 2000, he led the David Sarnoff Library as the Executive Director from 2000 until 2009. This collection includes advertisements from RCA and other companies for radios, televisions, phonographs, and other consumer electronics.

The David Sarnoff Library was established at the David Sarnoff Research Center in Princeton, New Jersey in 1967 as a showcase for the accomplishments of long-time Radio Corporation of America (RCA) head David Sarnoff. After five years of activity, the Library was largely moribund until the arrival of Alex Magoun as Curator (later Executive Director) in 1998. Under his leadership, the Library expanded its mission to include the history of RCA in general and the David Sarnoff Research Center in particular. Due to lack of funding, the David Sarnoff Library closed in 2009. The collection documents the creation and evolution of the Library through board of directors records, correspondence, reports, oral histories, and photographs.
