Diversity and Change in the National Historic Landmarks Program

Panel Discussion


This panel discussion focuses on current initiatives to identify and document National Historic Landmarks (NHLs) that represent the diversity and complexity of the American experience. Recently updated guidelines on preparing NHL nominations address issues related to diversity and relevance, and historic context studies assist in identifying potential NHLs associated with underrepresented themes and groups. A new initiative aims to increase recognition of women’s history in NHLs. Attendees are encouraged to propose and discuss other initiatives and studies needed to increase diversity and relevance in the study and interpretation of historic places.
