The CCSL reference collection is distinguished by its 300 yearbook titles from national, provincial, and city levels.

The collection also includes dictionaries, bibliographies, indexes and abstracts, statistical yearbooks, census reports for 1990 and 2000, biographical sources, and encyclopedias. This collection can be found in the CCSL reference room, where reference materials are denoted by red call number labels.

Reference materials may only be used in the library.
