The U. S. National Archives and Records Administration site has a some publications available online that are relevant to genealogy researchers.
The Reference Information Papers listing page has a number of interesting items for genealogists, including items such as:
- Using Civilian Records for Genealogical Research in the National Archives, Washington, DC, Area
- Military Service Records at the National Archives
- Black Family Research: Using the Records of Post-Civil War Federal Agencies at the National Archives
These are PDF files, so you will need an appropriate reader application.
My local branch, the Seattle office of the Pacific Alaska Region, page also has good information for local or visiting researchers.
