Defining a Global Historical Archaeology

Every historical archaeologist has at some point defined the discipline to the visitors at an archaeological site, a roomful of students, or a colleague or community member.  Most of us have a pretty clear notion of what distinguishes historical archaeology, and while it may diverge from what our teachers once told us, the conventional definitions in reference sources, or even the SHA’s own definition, we do seem to return to some consistent elements:  for instance, material things always seem to lie at the heart of what we do; most of us see ourselves as multidisciplinary scholars; we value rigor and replicability (even if we entertain sophisticated theory or are sometimes wary of being labeled a “science”); and we focus on peoples living in the last half-millennium or thereabouts.

Nevertheless, it is still completely reasonable that we have some distinctive visions of precisely what constitutes historical archaeology (or should define it) (compare the historical archaeology course syllabi definitions at the SHA Syllabi Clearinghouse).  The discussion over what defines historical archaeology has roots reaching over more than a half-century, and the dynamism of the discussion over our field is a good indication of historical archaeology’s dynamism and growth.  As the field now stretches its chronological boundaries into the contemporary world, encompasses an increasingly broad range of intellectual traditions, and pushes its geographic horizons to every reach of the planet, that discussion may be as lively as it was in the 1960s.  The SHA does not need to impose a definition of the discipline onto everybody digging something we might call historical archaeology, and in fact the discussion of the rich range of historical archaeologies is more important than forging a universal definition of the discipline that encompasses every time and place.  Instead, we need to continue to promote a rich discussion that reaches across global divisions, lines of historical difference and contemporary inequality, and moments in time.

The differences in conventional definitions of historical archaeology are perhaps most apparent outside the confines of North America.  As we prepare for our annual conference in Leicester in January, 2013 and then Quebec a year later, it is increasingly evident that what North Americans call historical archaeology goes by a variety of labels in Europe, Africa, South America, or the Pacific World: post-medieval, modern, and contemporary archaeologies all describe some scholarship akin to American historical archaeology.  Historical archaeology emerged at roughly the same moments in North America, the UK (with the Society for Post-Medieval Archaeology’s formation in 1966), and Australia (the Australasian Society for Historical Archaeology was founded in 1970).  All of these scholarly traditions push the conventional North American framing of historical archaeology in productive and exciting ways.

The most influential definitions of North American historical archaeology tend to revolve around the cultural transformations associated with Anglo and European colonization.  However, that definition looks out at the globe from the New World and has often somewhat ironically not examined the very European and African societies sending peoples to the New World.  For our European colleagues doing archaeologies of the last 500 years, the transformation into a post-medieval world reaches well into the medieval period and reveals dramatic variation from the Iberian Peninsula into central and northern Europe.  Pictures of Africa and Asia likewise have a historical depth that is not easily accommodated to a narrowly defined focus on European colonization alone.

Many historical archaeologists have focused on the ways in which emergent capitalism and colonization transformed the planet and provide an intellectual framework for historical archaeology.  Yet that sprawling profit economy was never utterly homogenous and integrated despite its global scale.  Capitalist penetration into New World colonies, Africa, and the breadth of Europe itself was inevitably variable across time and space, and archaeologists have particularly rich data to dissect the contextually distinctive spread of capitalism and local experiences of capitalist transformations.

The rapid growth of contemporary archaeology encompasses a breadth of research subjects that likewise stretches our conventional notion of historical archaeology.  William Rathje’s garbology studies laid much of the foundation for archaeologies of the recent past and contemporary world, and Americans have conducted a variety of modern material culture studies since the 1970’s taking aim on everything from electric cars to pathways of migration to wartime detention centers.  Archaeologies of the present-day world have been exceptionally active in the UK and Europe, where contemporary archaeologists have conducted creative, thoughtful, and challenging research on everything from wartime landscapes and prison camps (in Finnish, but video images) to Cold War materiality to punk graffiti.  For many of us this scholarship is intimately linked to historical archaeologies that have focused on more distant pasts and should have a clear role in a global historical archaeology that reaches firmly into the present.

The transformation to an increasingly global historical archaeology may be bearing the fruit envisioned by the very first historical archaeologists, whose January, 1966 gathering at Southern Methodist University was dubbed the International Conference on Historic Archaeology” (my italics).  In 1968, SHA President Ed Jelks (1968:3) intoned that “Historical archaeology has much to gain in the long run from encouraging a spirit of concerted, interdisciplinary, international cooperation.”  Many of our colleagues in the nearly 50 years since the Texas conference have been committed to a historical archaeology that always thinks of global systemic relationships beyond our local sites, but we are especially fortunate to live in a moment in which there is a rich international scholarship of the last half millennium that is increasingly accessible thanks to digitization.

Indeed, that global historical archaeology may well be SHA’s next horizon for growth in terms of both the society’s literal membership numbers and the discipline’s more significant expansion as a scholarly voice throughout the world.  Historical and post-medieval archaeologists are researching nearly every corner of the world and bring rich scholarly traditions distinct from North American anthropology.  That global historical archaeology is profoundly shaped by the concrete connections made possible through online scholarship and communication across a wired planet, and it bears significant debts to the SHA’s own commitment to conduct international conferences.

The Society for Historical Archaeology is only one steward for this rich international scholarship, and that scholarship is inevitably richer for including a broad range of global archaeological methods, scholars, and approaches.  International historical archaeology provides increasingly rich possibilities for the scholarly growth of historical archaeology that is increasingly globalized, compelling, and intellectually rigorous.

Primary Archaeology data for non-archaeologists?

This post is part of the May 2012 Technology Week, a quarterly topical discussion about technology and historical archaeology, presented by the SHA Technology Committee. This week’s topic examines the use and application of digital data in historical archaeology. Visit this link to view the other posts.

Is there value in exposing archaeological primary data to non-professional audiences? Can online archaeology databases serve broader goals? Can they both inform and serve as a tool for advocacy at time when the practice of archaeology is again being challenged in popular culture?

The National Park Services museum.nps.gov.

The National Park Service website, museum.nps.gov, is the online face of ICMS, the database tool that the Department of the Interior uses to manage its collections. In pre-launch testing the most common reaction was surprise that the parks actually had collections. Individual parks decide what to present on the website and it currently includes nearly 450,000 records, representing over four million objects, half of which are archaeological. Some information is removed before it reaches the web. Crucially for archaeology, this includes site name, site location, within-site provenience and UTM data; excluded to protect sites from the very real threat of looting, and at the request of Native American groups.

But stripping the artifacts of physical context before they reach the web is problematic at best for archaeology, so an attempt has been made to restore some contextual information. Collection highlights were developed to be used by the park staff to allow the grouping of objects, creating a virtual context that can represent a physical space – a site or an archaeological feature – or a thematic context, or a virtual exhibit. Fort Vancouver National Historic Site has created several highlights, including The Fort Vancouver Village. The highlight includes narrative text to explain the complex cultural landscape and is supported by 32 selected artifacts. Those artifacts are hyper-linked to the over two hundred thousand records which are part of Fort Vancouver’s online collection. I’d argue that even if most visitors never look at those records. they need to know that they are there. The National Park Service doesn’t just have great scenery, they have curated over forty million cataloged objects.

At Mount Vernon, George Washington’s Virginia plantation along the Potomac River, The South Grove midden excavation uncovered more than 60,000 artifacts. These represent almost 400 ceramic and glass vessels, hundreds of pounds of brick, mortar, and plaster fragments from renovating buildings, buckles, buttons, tobacco pipes, and more than 30,000 animal bones. A new website (in progress at www.mountvernonmidden.com) focuses on 400 objects, but the full database is there (and available on the Digital Archaeological Archive of Comparative Slavery site) and items are presented in the context of the wider collection. Additionally, the website includes a timeline, a map of the site in relation to the broader plantation landscape, historical notes and related published papers, and a database of the Washington family Invoices and Orders – all part of the larger data set that comprises the project.

So site databases, like the truth, need to be out there. Showing artifacts to the public, without this data-rich environment, suggests that just a few objects have primacy, elevating the qualitative over the quantitative. And if archaeologists want support for the process of archaeology and for digital preservation, then showing the volume of data makes sense.

The problem of exposing the soft underbelly of archaeological data is that at least some members of the public might start to question what’s presented. Why is it so hard to compare one site with another? Why are different methodologies used at different sites? Why does every project record different information? Why does the terminology differ between sites? There is a slow move forward in addressing all these issues (Kansa et al. 2011), but if archaeologists want to hammer home the point that pot hunting and looting are bad, then they should be willing to present and rationalize the datasets that professional archaeologists creates.

I’m not suggesting that advocacy is the only reason to show data. As text books and other electronic publications slowly transition from electronic copies of physical books into fully interactive media, perhaps they’ll also start to include accessible databases, and not just as appendices. Database could support graphs and result sets, allowing data to be manipulated, examined and even challenged. Perhaps eventually these datasets could be more than just one-way presentations of data. On websites, by recording the questions asked of the data, by tracking the datasets produced, these databases might come to be a part of research as well as publication.

Will today’s graduate training in Historical Archaeology predict the future of digital research archives?

This post is part of the May 2012 Technology Week, a quarterly topical discussion about technology and historical archaeology, presented by the SHA Technology Committee. This week’s topic examines the use and application of digital data in historical archaeology. Visit this link to view the other posts.

The Digital Archaeological Archive of Comparative Slavery (http://www.daacs.org/) provides standardized artifact, contextual, spatial, and image data from excavated sites of slavery throughout the early modern Atlantic World. Currently, DAACS is the largest archive, paper or digital, of standardized archaeological data related to slavery and slave societies. We have built it, with grant funds, generous data sharing, and intellectual input of more than 50 collaborating archaeologists and historians. For over ten years, these scholars and many others have contributed to DAACS’ overarching goal: to facilitate the comparative archaeological study of the spatial and temporal variation in slavery and the archaeological record by providing standardized archaeological data from multiple archaeological sites that were once homes to enslaved Africans.

DAACS strives to achieve this goal by giving researchers access to detailed standardized archaeological data in a format that allows the assemblages to be seamlessly compared quantitatively without any additional processing by the researcher.  We do so by physically reanalyzing the assemblages, and their associated contexts, to the same classification and measurement protocols that were established with the help of the DAACS Steering Committee in 2000. This is the critical aspect of the DAACS program—providing the standardized data that are essential to any comparative archaeological study.

DAACS data are stored in a massive relational Structured Query Language (SQL) database and are delivered over the internet via the DAACS website. The website debuted in 2004 with complete data sets from 15 domestic slave sites in Virginia. They were made available then, as they are today, through an easy-to-use, point-and-click query interface. By the end of 2012, DAACS will contain complete archaeological datasets, including data on over 2 million artifacts, from sixty sites of slavery in Maryland, Virginia, South Carolina, Jamaica, Nevis, and St. Kitts.

During the past year, over 10,000 unique visitors have landed on the DAACS website. Many DAACS users go straight for the Archive’s meta-data: the section of the website that contains information on the DAACS data structures and authority terms, DAACS cataloging manuals and stylistic element guides, and research papers and posters.  Others spend time browsing and reading through the archaeological sites pages, the text-heavy portion of the DAACS website that provides extensive background data on each site, site chronologies, access to images and maps, and bibliographies. We consider these pages essential to anyone using the archaeological data accessible through the DAACS Query Module.

Visitors often move from the background pages to the DAACS Query Module, which provides access to standardized data on hundreds-of-thousands of artifacts and archaeological contexts. The query interface masks a complex set of queries to the relational database that contains the raw archaeological data from all sites in the Archive. Queried data are returned and made available to users through the web browser and through downloadable ASCII files that can easily be imported into the user’s favorite statistical package.

DAACS is explicitly and clearly designed for large-scale comparative archaeological research. The website features—the Query Module, Archaeological Sites Pages, and corresponding meta-data—are critical to meeting the goals of the project.

In the evolving ecology of accessible digital data, digital archives vary in the extent to which they are designed to facilitate comparative research versus the extent to which they facilitate and make possible the preservation of archaeological data. These elements of online archives and databases are not mutually exclusive; many research archives preserve data and preservation archives encourage research. Projects such as tDAR (The Digital Archaeological Record) and ADS (Archaeological Data Service) are essential to the preservation of born-digital data generated by individual researchers. These critical resources preserve and make searchable data from any type of archaeological project, regardless of region or time period. Data from projects range from digital reports and basic finds lists to full-blown archaeological databases. However, there are comparability problems, to the extent that the contributing researchers use different classification and measurement protocols.

To date, research archives have focused on specific regions and time periods in order to provide datasets that enable researchers to address synthetic research questions. Examples include the Chaco Research Archive, A Comparative Archaeological Study of Colonial Chesapeake Culture, and DAACS. These projects provide a venue in which protocols that work well in particular times and places encourage individual researchers to think seriously about how to ensure their data plays well with others’ data, making it easier to researchers to glimpse the fruits of comparative analysis that shared protocols make possible.

But each archive type requires specific tradeoffs. For research archives making comparative quantitative research easy requires standardization.  However, it is not clear how, over the long-term, the requisite standardization will emerge. Sites like DAACS may be one way forward. No matter where one sits on the continuum, a firm commitment to open and transparent data sharing underpins all digital archiving projects.

The demand for archives that specialize in digital data preservation and accessibility will continue to grow as individuals, museums, universities, and the government grapple with archiving and making the large quantities of archaeological data they curate accessible. The success and growth of research archives that generate detailed comparable digital data accessible for the explicit research purposes will depend on how we meet the analytical needs of inquisitive archaeological researchers.

Over the past six years, we’ve seen a marked increase in the number of graduate students who approach us with the desire to pursue data-driven comparative research.  Their questions and needs may be a bellwether for the development, use and longevity of research archives.

Our experience at DAACS is that undergraduate and graduate students are eager to engage in archaeological data analysis, both on the single site and comparative levels.  They come to DAACS asking questions that require serious archaeological data analysis however many are missing two critical skills: the ability to link arguments about what happened in the past to archaeological variation and the skills in data analysis that allow them to summarize patterns in the data that speak to the arguments.

A concrete example is one related to chronology. Chronological control is the critical first analytical step in doing any archaeological study, whether at a single site or comparative analysis – you do not want to mistake temporal change for synchronic variation. Yet we have discovered that graduate students who have completed their coursework in Historical Archaeology do not know how to get started. From framing an argument to executing data retrieval, discovering patterns in the results, and linking those patterns back to the original argument we have discovered that most historical archaeology students come to us seeking advice on where and how to begin working with their data and the data in DAACS. An informal survey suggests that one reason is that only a handful of graduate programs that provide advanced degrees with specializations in historical archaeology require students to take even a single course in statistical methods.

But it is clear that students (and our colleagues) want more resources for learning how to work with these data. We receive regular requests to provide training in statistical analysis and to teach the more arcane analytical methods that we occasionally use but which are necessary to fully engage with the quantity of fine-grained data available through DAACS.

As the promise of using online databases for research has become increasingly obvious over the past five years, the demand for data has risen. It is how we meet the demand not only for the data but also for the analytical skills to make sense of the data that will determine the trajectory of online databases in the next 5 to 10 years.

While I worry about the trajectory of archaeological training, I remain sanguine about the promise of research archives in large part because I am lucky enough to work with graduate and undergraduate students engaging with DAACS’s online database, students who work doggedly to learn methods they were never taught, and who have come to realize that the data in DAACS are so rich that the hard work it takes to learn analytical approaches to their data provides big payoffs and exciting answers to previously unanswerable questions.
