Primary sources can be very important in doing historical research. These are documents of many kinds which were created during the period you are studying -- personal accounts like letters and diaries, newspapers, magazines & journals, books, government documents, and much more.
There is a separate guide to United States Historical Newspapers, and a Guide to Online Primary Sources that includes all kinds of primary sources in all subject areas. This guide is the US History subsection of that guide. To see more specific types of primary sources, mouse over the "Primary Sources" tab at the top of this page and look at the sections on personal accounts, historical texts, and primary source collections.
Additional published primary sources, collections of primary sources, and guides to primary sources may be retrieved systematically by subject keyword searches on UC Library Search. One generally effective initial search syntax is: [country or region or topic] [history] [sources], as in carolina history sources or southern states history sources or slavery history sources. To find specific types of published primary sources in subsequent search approaches, replace sources with one of these subject terms: diaries, correspondence, narratives, catalogs, manuscripts, archives, archival.
Brings together multimedia materials (text, archival primary sources, video and audio) around key environmental challenges, including climate change, water/air pollution, biodiversity, conservation, agriculture, deforestation and more. The database focuses on specific environmental case studies that enable students, teachers, and researchers to dive into particular, local problems and to investigate how solutions have been created (or not created) in globally scale-able ways. Each case study includes published text, films, documentaries, government reports, NGO publications, monographs, regulations debates, contextualizing resources, and archival primary sources, with an eye toward situating each case in its historical context and supporting continued interdisciplinary dialogue to invent multi-faceted and creative solutions for the future.
Primary sources are extremely important for historical research. They can be materials produced during the period you are researching: newspapers, other periodicals, even books, as well as letters, diaries, government publications and much more. There is a separate guide to U.S. Historical Newspapers and a separate Guide to Online Primary Sources in all periods of history. This page gives you a selection of primary sources selected for their value to research in U.S. History.
