These videos, tutorials and quizzes highlight the characteristics and significance of primary, secondary and tertiary sources.
Sources of information may be classified as primary, secondary, or tertiary. These categories reflect the originality of the materials and their relationship, or proximity, to their source of origin. Such categorization indicates whether the author of the resource is reporting or creating information first hand (primary source), or if they are conveying the experiences or opinions of others (secondary source).
Whether a source is considered primary, secondary, or tertiary depends on the focus of your research. For example, the Mellificium Chirurgiæ by Dr. James Cooke, 1667, was used as a medical reference manual and so, could be considered a tertiary source by its users. Researchers today however, may use Mellificium Chirurgiæ as a primary source to study the ideas, views, and practices of seventeenth century doctors.
Primary sources – objects, original documents or materials containing firsthand information about a topic. They are often one-of-a-kind or rare. When searching Library databases for these materials use the words 'sources' or 'documents' in combination with your topic. (i.e., "fur trade" AND sources).
Secondary sources – are about an event or primary source. Secondary sources describe, interpret, analyze, evaluate, explain, comment on, or develop theories related to the primary source. They are written after the fact, with hindsight.
Tertiary sources – list, compile, digest or index primary or secondary sources. They can be a good place to look up facts or get a general overview of a subject.
