In 2001, DePaul acquired approximately 1000 titles that had been in the ownership of Daniel, Jerome, and Philip Berrigan and Elizabeth McAllister to complement the receipt of the archival papers of the same individuals. The Berrigan Library is a valuable resource with a wealth of titles that promote scholarship in Catholic social justice. Also noteworthy is the marginalia, or notes in the margins, written by members of the Berrigan family in many of the titles, containing personal thoughts as well as notes about their own publications and personal actions in the Catholic social justice community.
Marginalia on front flyleaf of Killer, and other plays by Eugène Ionesco, inscribed by Daniel Berrigan, May 17, 1968. The inscription begins upside down on the title page and runs through two pages and the inside cover. The inscription is the original draft of the speech Berrigan made later that day at the draft board office in Catonsville, Maryland, where, with eight other activists (later known as the Catonsville Nine), he seized and burned draft records in protest of the Vietnam War, setting off a wave of similar protests throughout the country.
