Primary Sources
A primary source is the work itself being discussed, and also, in research, materials written or created about it during the period in which it was created. Primary works can include initial publication book reviews, diaries and letters, manuscript drafts, communication with publishers and collaborators, interviews, and speeches. In SuperSearch, use the advanced search to search by an author/creator to find his/her works and possibly collections of letters and other primary materials by that author. Using the keyword search finds everything associated with that author: both primary and secondary, and even tertiary items, which include encyclopedia entries and give the broadest overviews.
Secondary Sources
These include critiques and analyses not from the lifespan or shortly thereafter of a writer, or more broadly, the period of a literary movement. Journal articles and books that provide overviews fall into this category. Analyses of a particular work or an author's works over time- theoretical treatments using a cultural or political framework, such as New Historicism, feminism, colonialism, ecocriticism, or postmodernism, offering the author's interpretation, are secondary sources. In Super Search, you can narrow down your results by subject, or use the Advanced Search to search for your author as a subject.
Tertiary Sources
Reference materials are compilations of secondary and primary sources about authors, works, and literary movements. They consist of biographies, historical timelines, and compilations, such as anthologies similar to survey texts, and books such as the Dictionary of Literary Biography and the Twayne's Author Series. While these provide substantial background information and can include full book chapters of analysis (secondary sources) or excerpts from peer-reviewed journal articles, it's best to use these in tandem with primary and secondary materials. Information from reference sources is designed to provide context for further exploration of a topic.
