The second issue of the EWHADP database (and some figures with explanation and brief discussion) is available here. It contains basic information on over 2100 structures from 272 archaeological sites across the eastern United States and Canada.
The large majority of the increase in the number of entries in the database is attributable to incorporation of information from Ben Steere's dissertation (Steere 2011). Ben's data collection was focused on later (i.e., Late Woodland, Mississippian, and post-Mississippian) sites in the Southeast, and the new data reflect that. The database now contains many more sites in the South, particularly in Alabama, Georgia, and North Carolina.
There was some overlap between the datasets that Ben and I had assembled. I was careful to try to avoid listing the same structure twice, but mistakes are always possible. If you find any, please let me know.
Now that the basic data are altogether, I will spend some time (as I have it) checking what's in the database against the primary sources.
I have made some adjustments to the way structure shape is represented. I have plans to systematically collect data on architectural features of the structures. I would also like to start putting together a table of radiocarbon dates that will be linked to the main structure table. Data on associated features would also be nice, as would digitized versions of plan maps that could be used to more accurately estimate floor area.
