Advanced Search allows you to customize your search using specific search fields (also known as "properties" or "metadata fields"); please consult our explanatory list of available properties. Use the "Properties" pull-down menu to select from a range of available properties. Choose "All" to search across all available properties. Unless you know the exact term you are looking for, such as the formal version of a person's name (i.e. Kennedy, John F. (John Fitzgerald), 1917-1963), it is best to search using "CONTAINS" rather than "EQUALS". Of note: Advanced Search will search full-text versions of scanned documents, PDF transcripts of Oral History interviews, and finding aids.
