In the sciences, a primary source describes original research, while a secondary source analyzes or comments on a primary source or sources. For example, a research article is primary literature because it describes an original experiment and its results, while a review article is secondary literature because it collates multiple research articles to describe the current state of the field. A tertiary source is an index or consolidation of primary and secondary sources.

Books are are important in the sciences because they take a broader view of a topic that does a research article or a review article. When you are new to a topic or beginning a big research project (like a senior thesis or a literature review), starting with books is a better strategy than diving straight into research articles.
