From the University of Calgary's Arctic Institute of North America, the Arctic Science and Technology Information System (ASTIS) database "contains over 46,000 records describing publications and research projects about northern Canada." This service, which has recently been made free with help from the Canadian Polar Commission, covers all of the major branches of science. The simple and advanced search features lead to citations of Canadian government and industry reports, journal articles, conference papers, theses, and books, from 1978 to present. Citations contain bibliographic information, an abstract, detailed subject and geographic terms, and a library symbol to aid in locating a publication. The database also holds close to 11,000 descriptions of research projects conducted in Canada's three northern territories (Yukon, the Northwest Territories, and Nunavut) since 1974. Information about obtaining publications is provided at the search page.
