In 2004, the Kresge Law Library became one of the few academic law libraries to own more than 600,000 volumes. This was accomplished mainly under the tenure of the fifth law librarian, Roger Jacobs, who also served as head librarian of the Library of the United States Supreme Court. Between 2007 and 2008, a new building, the Eck Hall of Law, was constructed to provide the Law School with an additional 85,000 square feet of classroom and office space. In 2010 Robert Biolchini, alumnus and entrepreneur from Tulsa, Oklahoma, funded the renovation of the Kresge Law Library, located in the renamed Biolchini Hall of Law. The renovated Biolchini Hall is 106,500 square feet, has two 50-seat classrooms, a seminar room, 29 group study rooms, and holds 300,000 book volumes and more than 300,000 volumes in microfilm. The total cost of renovations and expansions was approximately 58 million dollars.
