The CCI Library has one of the largest conservation and museology collections in the world. The collections are regarded as an important source for conservation and museology literature on a wide variety of topics, such as preventive conservation, industrial collections, architectural heritage, fire and safety protection, museum planning, archaeological conservation, preservation in storage and display, exhibition design, disaster preparedness, and museum education. The holdings include a large selection of books on textiles, furniture, paintings, sculptures, prints and drawings, and archaeological and ethnological objects
The CCI Library also disseminates information by contributing references to two international databases: BCIN, the bibliographic database of the Conservation Information Network, and BMUSE, the museology bibliography database. Both databases are operated by the Canadian Heritage Information Network (CHIN), a Special Operating Agency of the Department of Canadian Heritage.
The CCI Library is open to the public only by appointment.
