Genevieve Trainor writes: “The Guinness World Record holder for Most Prolific Book Thief is Ottumwa (Iowa’s) Stephen Blumberg. The 23,600 volumes he accumulated between the 1970s and his arrest in March of 1990 were all stashed in his 17-room home. Creighton University in Omaha, Nebraska, got involved with Blumberg as part of the FBI’s efforts to return the stolen manuscripts and rare books to their museums and libraries. Referred to as the Omaha Project, the information science proving ground involved four weeks, 44 catalogers and reference librarians and 600 volunteer hours to determine who might be the rightful owners.”
