Historiography
Historiography refers to the study of how history is written, the methods employed by historians, and the changing interpretations of the past over time. It encompasses both the history of historical writing and the critical analysis of historical works. Understanding historiography is essential for situating one's own research within ongoing scholarly conversations and recognizing how interpretations are shaped by the contexts in which they are produced.

Primary Sources
Primary sources are documents, artifacts, or other evidence created during the historical period under study. These include letters, diaries, government records, newspapers, photographs, and material objects. Primary sources offer direct, contemporary evidence of past events and experiences, though they must be critically evaluated for bias, authenticity, and representativeness. The Technical Deep-Dive section provides detailed guidance on source criticism and evaluation methods.
Secondary Sources
Secondary sources are works that analyze, interpret, or synthesize primary sources. These include scholarly books and articles, textbooks, biographies, and historical documentaries. Secondary sources mediate access to the past through the perspectives of other historians and are essential for understanding the current state of scholarship on any topic. When conducting research, historians typically survey secondary sources before turning to primary materials to understand the existing historiography.
Archives
Archives are repositories that preserve historical records and make them available for research. Archives may be maintained by government agencies, universities, historical societies, or private organizations. The National Archives and Records Administration (NARA) is the primary repository for federal government records in the United States, while state archives, presidential libraries, and special collections at universities preserve state, local, and personal papers.
