There are also agreements for state and international documents. Both Duke and UNC-CH collect the publications of other international organizations extensively. In terms of federal documents, UNC-CH is the regional depository for the state of North Carolina, and NCSU is the Patent and Trademark library for the state. There have been cooperative purchases of commercial products facilitating the use of the federal documents collections. Duke and UNC-CH cooperate on acquiring foreign and domestic newspapers in paper and microfilm.
Foreign newspapers tend to reflect the area studies cooperative agreements.
Libraries have sometimes acquired microforms jointly, as they did with the Landmarks of Science. Both Duke and UNC-CH acquire unique manuscript and archival collections documenting the American South. In addition, Duke's Special Collections Library builds on its holdings of printed Southern Americana, especially through the acquisition of titles in religion, social and cultural history, and literature, including titles from small literary presses. NCCU has unique collections in African-American juvenile literature. NCSU covers the applied sciences, including Southern agriculture and textiles.
