Tourism, Preservation and Race in the US

Related to an ongoing Travel Office project, I've been doing some reading into the intersections of historic and ecological preservation, tourism and race. Two books that I've discovered relatively recently, Black Geographies and the Politics of Place and Mapping Tourism, have provided a lot to consider.
In Black Geographies, Angel David Nieves' "Memories of Africville" looks at the black settlement known as Africville in Halifax, Nova Scotia through the disparate discourses of historic preservation and the reparations movement. One notable statistic Nieves uses: of the 76,000 properties identified by the National Register of Historic Places, only 823 are associated with African American Heritage. This is due largely to the fact that historic preservation is overwhelmingly based on notions of architectural integrity, meaning that preservation as an institution is biased towards building a record of architectural style and technology. Nieves' argues that "developing and alternative methodology adapted to grasp the multiple meanings of 'difference' in the North American cultural landscape and concurrently articulating a new model for historic preservation require new modes of interpretation." An argument is also made that for the creation of historical registers as an element of reparations. An unexpected and very interesting aspect of the text is how the debate between preservation and recreation has an effect on what is included in the historical record.
In Mapping Tourism, Owen Dwyer's "Memory on the Margins" looks at the politics of Civil Rights tourism, specifically the Alabama Civil Rights Trail. Dwyer analyzes the aesthetic of the map created for the trail, and how it positions Civil Rights as a "won cause" that took place in isolated Southern Cities, privileging streets, pulpits and courtrooms at the expense of homes, neighborhoods and citizenship schools. This division, according to Dwyer, represents a marginalization of the role of women in the black freedom movement. The discussion focuses on maps, institutions and literature that serve as gatekeepers, controlling access to sites and their histories. The Student Nonviolent Coordinating Committee, for example, is not recognized by the Alabama trail, despite its central role in the movement. Dwyer writes:

The symmetrical authority of maps and monuments - in one case generated via claims to scientific accuracy, in the other by recourse to weighty materiality - stands in stark contrast to the inherent instability of the messages they bear... this contrast between apparent fixity and radical impermanence accounts for the political value of maps and monuments as representational capital.

This interpretation of the value of maps and monuments is what drives the Travel Office's continued interest in tourism as a site of analysis and intervention.
The US National Park Service's Cultural Resource Management publication contains some official analysis and policy positions that are of interest here, especially Antoinette Lee's "Cultural Diversity and Historic Preservation."
