N.C. Gen. Stat. § 125-11.7: State Library designated the official depository for all State publications.

The State Library shall be the official, complete, and permanent depository for all State publications, and shall receive five copies of all State publications in addition to the copies required for the depository system: Provided, however, the State Library shall receive only five copies of any State publication offered for sale by a State agency at a price at least high enough to recover production costs: Provided, further, the State Library, notwithstanding the definition of "State publication" contained in this Article, shall have authority to exclude from required deposit in the State Library any items or materials which it finds are not appropriate for deposit.
