State and five area colleges (Meredith College, Shaw University, Peace College, St. Mary's College, and St. Augustine College) established the Cooperating Raleigh Colleges Program, allowing direct borrowing of library resources among the six campuses. On July 1, Acting Director Littleton was confirmed as Director. On December 8, closing hours were extended from 11 p.m. to 1 a.m. During the summer and early fall of 1967, unknown thieves stole "at least 16 sets of journals and bibliographical works" from the Library, including two valuable sets of 18th and 19th-century botanical journals, comprising 100 bound volumes. As a result, a security checkpoint was installed at the bookstack entrance on February 12, 1968. Construction on a new 10-story bookstack tower began on November 18. In 1970, the same year library holdings passed 500,000 volumes, William V. Frazier was hired as the library's first African-American librarian and William C. Horner became the first systems librarian. Frazier had previously been a sociology instructor and assistant reference librarian at NCCU.
