Commemoration: The American Association for State and Local History Guide serves as a handbook for historic site managers, heritage professionals, and all manner of public historians who contend daily with the ground-level complexities of commemoration. Its fourteen short essays are intended as tools for practitioners, students, and anyone else confronted with common problems in commemorative practice today. Of particular concern are strategies for expanding commemoration across the panoply of American identities, confronting tragedy and difficult pasts, and doing responsible work in the face of persistent economic and political turmoil. A special afterword explores the role of emotion in modern commemoration and what it suggests about possibilities for engaging new audiences.
