As defined in LAC's Collection Development Framework1, publications are considered to be of "heritage value" if they reveal typically Canadian experiences or stories; document events or trends (cultural, political, economic, social, demographic, scientific and religious) with a national scope; provide valuable insights into the activities of a diverse and developing society; or are of a rarity and importance that allows them to be considered national treasures.
The particular areas of emphasis in terms of Canada's published heritage are: aboriginals; multicultural communities; Canadian literature; Canadian music; and the historical approach to the development of Canadian society (HADOCS). The latter category, HADOCS, includes all aspects of aboriginal culture including the impact of European contact, the exploration and settlement of Canada, economic development; political systems; Canada's foreign and international relations; social and cultural life; as well as atlases of Canada.
Apart from publications intended for most LAC's special collections, full-level cataloguing treatment should be reserved for publications that are of heritage value within the areas of emphasis. The decision that a publication falls within an area of emphasis and is of heritage value is usually made at the point of acquisition. The level of cataloguing treatment, however, may be adjusted by the cataloguer based on factors such as the publication's currency or national significance, and taking into account the operational resources to meet the objective of cataloguing all new acquisitions within established turnaround times.
Full level cataloguing treatment should be limited to publications of heritage value that meet two or more of the following criteria.
