Books and Pamphlets

In most cases, books can be considered a secondary source because the author is using evidence from other sources to support their argument. However, books can be considered a primary source in some disciplines; published memoirs, autobiographical work, a bound collection of documents, or creative writing could all fall under the primary source category. Likewise, pamphlets or small, bound booklets or leaflets on one particular subject, are typically a primary source.
