Library of Congress subject specialists have created research guides that provide background and resources for further study.
In addition to the research guides arranged here by subject category, you can also examine related topics under Legacy Guides. These older guides have not been updated, but still provide essential information on genealogical research at the Library of Congress. As these guides are updated, they will migrate onto the appropriate subject page.
Since family history is human history, you can also browse a complete list of research guides from across all divisions of the Library to learn more about the many unique subject areas that may have impacted the lives of your ancestors and their communities.
