Digital Antiquity wants to remind you that Saturday, October 20th is National Archaeology Day, an annual event organized by the Archaeological Institute of America (AIA). Archaeological organizations throughout the US and abroad will sponsor programs designed to engage the public in local archaeology.  Here in Phoenix where our offices are located, the Pueblo Grande Museum will offer free admission all day!  They have a number of exciting events planned, including a special Archaeology for Kids program, site tours, cooking demonstrations, and an opportunity to observe volunteer mudslingers repair the platform mound.

Round out your day by exploring tDAR’s extensive collection of Pueblo Grande material online.  Our archives are always available for research and education about archaeology in your neighborhood or across the globe.

How do you plan to celebrate National Archaeology Day? Visit the AIA’s National Archaeology Day website to locate archaeology events and activities happening near you.  We hope you get out and get dirty!

The American Anthropological Association (AAA) has recommended tDAR as a digital repository for  archaeological data archiving.  In the September 2012 issue of Anthropology News, Robert Hahn, chair of the Grey Literature subcommittee of the Resource Development Committee wrote: 

AAA…encourages archaeologists to deposit data and the related publications that make that data meaningful in the Digital Archaeological Record (tDAR) Available at, tDAR is an international digital archive and repository that houses data about archaeological investigations, research, resources and scholarship. It has a plan for long-term preservation and ongoing access to digital data.

If you have archaeological data you’d like to upload we encourage you to visit tDAR today!  Becoming a registered tDAR user is easy, and allows you to upload to and download from our extensive collections of archaeological information.  Now is a great time to contribute your archaeological records to tDAR as upload fees are waived for individuals through the end of the year.

Digital Antiquity was founded with two basic goals in mind: (1) provide broad and easy access to archaeological data and documents and (2) ensure the long-term preservation of digital archaeological information for future use.  In July Arizona State University Libraries and Digital Antiquity signed an agreement to ensure that tDAR’s records would remain accessible and be preserved even in the event that Digital Antiquity is unable to continue to support tDAR’s development and maintenance.  This formal Memorandum of Agreement reinforces our commitment to provide a sustainable digital repository dedicated to serving the information access and preservation needs of the archaeological community.


In 1960, at its annual meeting, the Society for American Archaeology authorized the establishment of a new publication series making use of Microcards as the medium of publication. This move toward a condensed, durable, and accessible medium of publishing archaeological data and reports was viewed as a new approach to preservation technology in 1960. The University of Wisconsin was chosen to publish the series and a total of 29 archaeological reports on Microcards were published between 1960 and 1967 as the Archives of Archaeology series. Joseph Tiffany, Professor of Anthropology at the University of Wisconsin-La Crosse and Executive Director of the Mississippi Valley Archaeology Center, details the process undertaken to digitize the 29 volumes in his article “Digitizing The Archives of Archaeology Series,” published in the May 2012 edition of the SAA Archaeological Record. Today, the Archives of Archaeology series has been integrated into tDAR (the Digital Archaeological Record) in keeping with the original publication’s goals for preservation and access. These archaeological reports, with analysis and descriptions of archaeological investigations and resources from Central America to Alaska to Japan, are reproduced digitally and in their full form in tDAR. Now these once relatively obscure reports are available for access at any time via the Internet. The entire list can be viewed as a tDAR collection at Individual reports can be accessed in tDAR using the list at the bottom of this news item. These archaeological reports contain data that has never been published before in a widely circulating format. They include early investigations into the effects of climate change on prehistoric peoples in Iowa, full survey reports from the 1959-1962 Southwest Archaeological Expedition of the Chicago Natural History Museum (also known as the Field Museum) in eastern Arizona, and a first look at English-translated Japanese archaeological reports that are foundational in current understandings of pre-ceramic Japanese occupations. Examine some of the archaeological documents here:

It is interesting to note that the original intent of the Archives of Archaeology Microcard publication program, to provide an easy and reliable means of access to detailed archaeological reports, is now being fulfilled by a new technology. The Center for Digital Antiquity, which maintains tDAR, has as its mission providing for access to archaeological information and ensuring its long term preservation.

Digital Antiquity Technology Director Adam Brin and Executive Director Francis P. McManamon are co-contributors to the Society of Historical Archaeology’s  May 2012 Tech Week Blog. This week’s blog topic, hosted by the SHA Technology Committee, examines the use and application of digital data in historical archaeology. Brin and McManamon, along with representatives from “Stories Past”  and the Digital Archaeological Archive of Comparative Slavery (DAACS), were invited to comment on the future of online databases and data sharing, the role played by their organizations in the larger field of archaeological data sharing and online databases, and the major hurdles that stand in the way of wide-scale acceptance and use of online databases in the archaeological community.

In their commentary, Brin and McManamon review the challenges and opportunities with archaeological data access, use, and preservation, sharing their concerns and solutions for sustainability of digital repositories. They support and encourage the notion that the archaeological community, together with technologists, can build tools that digitally preserve important archaeological data and make it accessible for analysis and re-use in ways that could only be dreamed of in the past.  The blog, “Sustainable Archaeological Databases – a view from Digital Antiquity” posted on May 29th, 2012.

Working with digital curators at the Center for Digital Antiquity, the University Press of Colorado has added to the Digital Archaeological Record (tDAR) information about 27 of its books on archaeological topics.

The subject matter of the books includes a wide range of topics and locations, including the Maya area, Amazonia, Colorado, and the American Southwest.  Registered tDAR users may download the books’ tables of contents and introductions from the tDAR record.

One of the most recent books in the UPC catalog, Surviving Sudden Environmental Change: Answers from Archaeology, edited by Jago Cooper and Payson Sheets, may be downloaded in its entirety,

This arrangement adds to the archaeological information already available through tDAR, whose content is indexed for searches by Google and other main search engines, and exposes the University Press of Colorado’s archaeological catalog to searchers who otherwise may be unaware of its available books.

You can find the tDAR collection that lists the UPC publications here.
