Content and Context: Visualizations for the Public?

In the very useful survey of the “history web” in their 2005 book Digital History: A Guide to Gathering, Preserving, and Presenting the Past on the Web , Dan Cohen and Roy Rosenzweig identify the range of genres that encompassed the historical content on the web: archival sites, exhibits and scholarly essays, teaching and learning sites, and discussion forums and organizational sites. Even though Cohen and Rosenzweig failed to account for the way that blogs, YouTube, and social media would eventually permeate the history web, I like their categories because they continue to the give us a way to think about what we do when we create public history online. We tend to provide access to collections, to offer interpretation, to offer instruction, and to offer a forum for conversation, both general and professional. So, as I began to think about the critical issuing in effectively using data visualizations in public history, I wanted to consider them in relationship to the activities above. Since Sheila has already written a great post on collections and enhancing access with visualizations, I’d like to focus both on their interpretative and instructive use, building on Trevor’s thoughts from his last post on discovery and communication.

For public historians, the mode of online outreach that has the longest history is that of interpretative exhibits, whether as companions to a physical exhibit or as independent works of scholarship. Despite the liberating possibilities for disjunction, many of exhibits hue very closely to the linear narrative structure of traditional narrative history.  In doing so, they have demonstrated varying degrees of success in offering the public a glimpse of the richness of the past. Two sites from the National Museum of American History demonstrate the wide range of approaches. Both “The Price of Freedom” and “A More Perfect Union” are beautiful sites, but one presents a linear and reductive narrative of military history and the other presents the difficult topic of Japanese internment during World War II with a range of voices and perspectives that highlights historical complexity. The difference here is in the effort to bring together evidence in a user interface that allows for the consideration of many perspectives and multiple causality, as opposed to offering a single perspective that simplifies the past.

Successful or unsuccessful, most exhibit sites have the benefit of offering visitors a range of contextual information in both the text of the basic narrative and in the descriptions that accompany individual artifacts, images, or documents. This contextual information is essential for a public who may not have a deep background to bring to their encounter with primary historical materials. Data visualizations can short circuit the tendency to present simplistic narratives about our collections. Unfortunately, however, data visualizations that concentrate the user interface into a single interactive screen can also significantly reduce our ability to offer the public necessary historical context if we’re not careful.

Take, for example, the great interactive correspondence visualization created by the historians and computer scientists at Stanford for the Mapping the Republic of Letters project. This complex interface really only makes sense to individuals who are content experts, and sometime then only after they’ve read the accompanying pdf explaining the different facets of the tool. For a content novice, the tool is little more than a colorful toy because it links to primary sources in a subscription database, and because it lacks the biographical data on the correspondents that might make their network connections intelligible. If the visualization included access to a larger context of the enlightenment and background on the individual correspondents, it could be a powerful and concentrated way for the public to learn about the development of this period in Euro-American intellectual history. To some extent, we can excuse the Stanford project because it is explicitly a research venture targeting scholars of the enlightenment, rather than members of the general public

The Digital Vaults site from the National Archives and Records Administration, on the other hand, was created precisely to engage the public. Unfortunately, the project is completely hampered by its abstraction. The Flash version of the site gives users access to a seven randomly selected sources from a database of over 1,200. Clicking on a document, the user enters a web of connections to other documents based on shared tags. (The HTML version simply offers an alphabetical list of tags.) The sources have minimal accompanying metadata–usually title, date, and a brief description. While this environment is attractive and fun to play with, it fails to offer users enough context to make any historical sense out of the materials they encounter. Rather than offering and entree into NARA’s rich collections, the site leave users at sea with only their pre-existing historical knowledge to support them.

Unlike Digital Vaults, visualizations that make use of geospatial and temporal cues offer users more necessary orientation. One successful example is Minnesota Historical Society’s True North project, which offers users the ability to layer information in space in time to glean some understanding of the state’s history. While the interface does not link out to individual primary sources, it manages to offer enough cohesiveness that users can start to construct their own narratives of change. The National Museum of Australia’s History Wall is even more successful. Built on the backbone of a flexible timeline, the interface allows users to explore the lives of Irish in Australia between 1770 and the present, drawing on, among other things, the Australian Dictionary of Biography, and amazing Trove database that aggregates over 280 million sources from National Library of Australia. Together these elements let a user to explore within a much more deeply layered context that can push them to use heuristics that are important to historians as they make sense of the evidence from the past.

Considering this range of examples, I hope that we can begin to have a conversation about how to create and frame data visualizations that provide the public with new ways to access our content but also offer them enough context to help them begin to make sense of those materials in meaningful ways.

  1. Sharon – a very nice survey of some of the challenges of organization faced when presenting historical material online.

    The narrative linear history has its appeal – I’m convinced it’s how most people think about the past, and timelines are easily understood. That’s why, say, Price of Freedom, with its backbone of wars, makes sense to visitors. You know where you are at any given time. You lose nuance, but gain certainty. Not quite fair to compare it to More Perfect Union; that covers a few years, and layers on many more stories.

    I had not see the Digital Vaults project before, but it strikes me as being more game than teaching tool. The thumbnails are too small to see enough to understand the images; you’re reduced to a guessing game. I wonder what would happen if this were on a touch table, and if each document came with a short summary, or keywords – you could get a better sense of the documents at a glance, and maybe start to form a better understanding of how a historian might develop an intuition about historical connections. As it is now, like you say, there’s not enough context.

    The Australian Irish timeline adds some discovery and randomness to exploring history. I’d be curious to know how much is preset – how many of the events and people and stories and objects – are selected by a historian, and how much is based on the sliders and the name given by the user. One thing that’s appealing is the way it’s built on the page; it keeps your attention!

  2. I think that was my point about Price of Freedom, Steve. To deliver history that includes only that single, linear march of certainty across three centuries (we fight wars for freedom…) does the public a disservice. Like a More Perfect Union, they deserved the layers of many voices (we fight wars for freedom, to stop genocide, for territory, for greater access to natural resources, for economic gain, etc…).

    And, I’m fairly sure that we can get Tim Sherratt to comment on the mechanics at work in the history wall. My recollection is that it is a javascript tiling of the filter returns across the several databases.
