The books are arranged according to their classmarks in the Cambridge University Library Classification System for Chinese Books. Large volumes (over 29 cm.) are shelved in a separate sequence on Ground Floor cases 16-17 and 101-103 and Basement cases 144-145 and 160-161. Due to space constraints, some volumes are shelved out of sequence; the new locations are indicated on cards inserted at the appropriate places on the shelves.
Books which stand on open access on the Ground Floor (class FB) and the Basement (class FA) of the Aoi Pavilion may be borrowed by readers who have borrowing rights.
Books in class FB which stand in the East Asian Reading Room (marked Not to be taken out) are reference works and may not be removed from the Room without permission from a member of the Library staff.
Withdrawn books in classes FA and FB and all books in classes CRA-CRZ and FC (the Wade Collection), FH (Rare and Reserved Items) and FM (Unbound Books) must be requested by completing an Order Form at the Enquiry Desk in the East Asian Reading Room. These books are not ordinarily borrowable and may only be used in the East Asian Reading Room.
