On 2 April 2000, the Board of Directors of the Organization of American Historians also approved these standards. The American Historical Association is in the process of reviewing and considering the standards as well. In a democracy, a knowledge of history forms the context in which citizens make informed decisions. Historical knowledge also provides personal, family, and community links to the past. Historical understanding of other societies assists individuals in identifying commonalities in the human condition and in negotiating the differences that exist in our increasingly pluralistic world.
Museum exhibits play an important role in the transmission of historical knowledge.
They are viewed by citizens of diverse ages, interests, and backgrounds, often in family groups. They sometimes celebrate common events, occasionally memorialize tragedies or injustices, and contain an interpretive element, even if it is not readily apparent. The process of selecting themes, photographs, objects, documents, and other components to be included in an exhibit implies interpretive judgments about cause and effect, perspective, significance, and meaning. Historical exhibits may encourage the informed discussion of their content and the broader issues of historical significance they raise . Attempts to suppress exhibits or impose an uncritical point of view, however widely shared, are inimical to open and rational discussion.
