The Canadian Institute for Historical Microreproduction (CIHM) microfilms Canadian monographs and pamphlets dating before 1900, providing microfiche copies of the materials for distribution. A catalog of the material cumulates annually on computer-output microfiche. Cataloging data are available through the National Library of Canada, UTLAS in Canada, and OCLC in the United States. The original materials are carefully taken apart during the reproduction process to preserve the original document. -- AATA
