Tertiary sources are a type of information source that compiles and synthesizes information from primary and secondary sources. They are generally considered to be the most removed from the original event or research. Examples of tertiary sources include encyclopedias, dictionaries, textbooks, and review articles. Their purpose is to provide a broad overview of a topic, often summarizing existing knowledge and presenting it in an accessible format. Tertiary sources are useful for gaining a general understanding of a subject and identifying relevant primary and secondary sources for further research. However, they are not typically used for in-depth academic research as they may lack the original detail or nuanced analysis found in primary and secondary sources. When evaluating information from a tertiary source, it's important to consider the author's credentials, the publication's reputation, and the date of publication to ensure accuracy and relevance.
