Buried deep inside an article about many different (and unrelated) things, there is this brief mention:

After more than a decade, the head of the National Archives and Records Administration retires. April 30 was David Ferreiro’s last day as archivist of the United States. He led NARA since being confirmed in late 2009 during President Barack Obama’s first term. During his 12 years in charge, Ferreiro oversaw a major shift from paper to electronic recordkeeping. Ferreiro also led the establishment of the Citizen Archivist program that allows volunteers to transcribe and tag records.

Deputy Archivist Debra Wall will serve as the acting archivist of the United States until the White House selects a permanent replacement.
