New ITA Publication

Cultural resources management (CRM) reports represent a rapidly growing proportion of our knowledge associated with archaeological undertakings in the United States. Historically, these reports were printed in limited numbers and distributed to a few libraries and individuals, and few were distributed beyond the political boundaries of any given state. Libraries on the distribution list are reticent to allow patrons to check out these reports due to the fact that they have—and will only ever have—a single copy. Late in 2009, the Texas Historical Commission (THC) permitting guidelines for CRM reports were updated, requiring CRM contractors to submit a digital copy of a redacted (no site locations or photographs of human remains) report before their permits could be closed. These reports, the lion’s share of which were funded with public monies, were meant to be made publicly accessible and should be available.

The Index of Texas Archaeology (ITA) is your source for open access archaeological reports from projects conducted throughout the State of Texas. The digital reports can be read on the ITA site or downloaded to your computer at no cost. All authors retain, at minimum, a Creative Commons Attribution license to their work, meaning that they, and in some instances the funding agency, must be credited for original creation.

Licensing information can be found on the cover page for each report. All reports are organized by year (Volume No.), and can be accessed using the drop down menu in the right column. To begin searching for archaeological reports from your area, enter a term in the search bar or click on the Advanced Search tab at the bottom of the right column.

Using the suite of tools available to us through bepress means that the Index of Texas Archaeology (ITA) is archived in Portico, and that our content is indexed by Google, Google Scholar, CrossRef, and Altmetric. Digital object identifiers (DOIs) are being assigned to each report using CrossRef, whereby both the report and the references that each report cites—those that have a DOI—are indexed (view ITA records on CrossRef here).

In addition to CrossRef, we are also working with bepress to integrate CrossMark, which will allow readers to ensure that they are citing the most up-to-date content. Any changes in the published version will be noted in the metadata, which can be accessed by clicking on the CrossMark logo. We are also working through the process of implementing the CrossRef API to include cited-by linking, where readers will be able to view those publications that cite each of the ITA reports. This manner of increased accessibility and distribution also helps to ensure that report authors, and those authors whose work is cited in the reports, receive full credit—and accessible metrics—for their efforts, similar to their colleagues in academia.

While pursuing a study of 3D geometric morphometrics for ceramic burial vessels that often articulate with the Native American Graves Protection and Repatriation Act (NAGPRA) from the ancestral Caddo region, there have been no shortage of potentially meaningful observations, one of which–rotational asymmetry in coil-built vessels–is discussed in this publication. Using Geomagic Design X (reverse-engineering software) and Geomagic Control X (computer aided inspection software), metrics associated with rotational asymmetry were generated then analyzed.

Vessels can be sectioned, where the deviations for a specific spline can be extracted for a more in-depth analysis.

Results indicate variable asymmetry among the different vessel shapes (i.e., bottles, jars, etc.), which may augment and strengthen studies and discussions of vessel form. Future directions include the incorporation of directional and–possibly–fluctuating asymmetry measures for the widest vessel profiles. Preliminary results point toward substantive analytical gains that can be used to augment more traditional ceramic analyses as well as geometric morphometric studies of ceramic vessel shape.

Results of the asymmetry analysis.

In addition to the analysis of rotational asymmetry, there is a brief discussion for analyses of (directional and fluctuating) asymmetry using geometric morphometrics. While the bulk of that discussion remains the topic of another paper, the citation network for asymmetry studies that use geometric morphometrics was included in this paper, and can be accessed by clicking on the image or the link below.

Many thanks to the Caddo Nation of Oklahoma for the requisite permissions needed to scan the vessels, and to the Anthropology and Archaeology Laboratory for access.
