As part of our 50th anniversary celebration Lincoln Boyhood National Memorial is hosting a conference focusing on the 27 "memorial" sites within the national park system. We will examine their history, and how they serve as tangible evidence of the ways our collective memory undergoes change and is sometimes influenced by more than a pure desire to objectively preserve our history. We will examine such questions as: Why did they receive this designation? Are there commonalities between the sites? Are there special challenges to administering and interpreting such sites as opposed to those with different designations? What do they say about how we remember and commemorate our history?
