Primary sources are easy to find.
You can introduce your students to many topics and use primary sources to teach across the disciplines. Because primary source documents are created by people, they were produced with a specific perspective, purpose, and interpretation. Some materials are hybrids because they display characteristics of both secondary and primary sources. Examples include photographs, newspapers, and edited collections of diaries, letters, and journals. Students, in examining all types of information, bring their own experiences, opinions, and perceptions to their efforts.
