On July 28, 2009, President Obama nominated Ferriero to be 10th
Archivist of the United States. An early October confirmation hearing was scheduled by a subcommittee of the
Senate Committee on Homeland Security and Governmental Affairs. According to the subcommittee chairman, Senator
Thomas Carper of Delaware, Ferriero's quick confirmation by the Senate was never in doubt. Ferriero used the public occasion to express his view that the National Archives was at a "defining moment with regard to our existing electronic records, social media communications, and emerging technologies being used throughout government offices." He also noted "issues of collection security, the future of the Presidential Library system, backlogs in processing, staff job satisfaction, stakeholder relationships, preservation and storage needs." He was confirmed by the U.S. Senate on November 6, 2009; he was sworn into his new office on November 13, 2009. President Obama appointed Ferriero to simultaneously head the new
National Declassification Center, which had "been given four years to go through 400 million pages of federal documents that remain top secret. They date to
World War I." On January 13, 2022, Ferriero announced he would retire effective mid-April 2022 after a twelve-year tenure as Archivist of the United States. He urged President Biden to "not hire another white male" to replace him, and said that he chose to retire at that point so that Biden could be the one to name his replacement. Ferriero's retirement was effective on April 30, 2022, and Deputy Archivist
Debra Steidel Wall took over as
acting Archivist of the United States.
Relationship with Wikipedia As part of his tenure at the National Archives, Ferriero took an active interest in working with Wikipedia, of which he has called himself "a huge fan." When questioned about the National Archives' engagement with Wikipedia, his response was that "the Archives is involved with Wikipedia because that's where the people are." Under Ferriero's aegis, the National Archives worked with the
Wikimedia Foundation since 2009, having had a
Wikipedian in Residence and uploaded thousands of images to
Wikimedia Commons. He quoted a blogger in saying: "If Wikipedia is good enough for the Archivist of the United States, maybe it should be good enough for you."
Censorship of archival imagery In January 2020, Ferriero supported the Archives' decision to censor a photograph containing
signs critical of
President Trump and references to women's anatomy in an exhibit devoted to the centennial of
women's suffrage in the United States.
The Washington Post reported that Ferriero "participated in talks regarding the exhibit and supports the decision to edit the photo." The alteration of the image was immediately criticized by historians, with
Douglas Brinkley saying "to confuse the public is reprehensible. The head of the Archives has to very quickly fix this damage." Subsequently, the National Archives issued an apology for the decision and promised to restore the original image and review its exhibit policies. ==Personal life==
