The purpose of this work is to provide librarians and students with a guide to Canadian reference material divided into the following fields: general reference works, the humanities, science, and the social sciences. It is a selective guide only, and does not aim at completeness. The material covers Canada in general, the ten provinces, the territories, and three cities -- Ottawa, Montreal, and Toronto. No geographical area smaller than a province, with the exception of the three cities named, is considered. However, the emphasis is on Canada in general, the provinces receiving coverage in certain selected subjects, and the three cities receiving merely a token coverage. Reference works such as those dealing with individuals or with particular laws have been excluded. New editions and new works up to December 1971, which have come to the attention of the editor, have been listed. A subject, author and title index is included. (Author/DH)
