Session 510: Digital History and Digital Collections (aka, a fan letter for Roy and Dan)

There were lots of interesting ideas in the talks given by Dan Cohen and Roy Rosenzweig during their SAA session Archives Seminar: Possibilities and Problems of Digital History and Digital Collections (session 510).

Two big ideas were discussed: the first about historians and their relationship to internet archiving and the second about using the internet to create collections around significant events. These are not the same thing.

In his article Scarcity or Abundance? Preserving the Past in a Digital Era, Roy talks extensively about the dual challenges of loosing information as it disappears from the net before being archived and the future challenge to historians faced with a nearly complete historical record. This assumes we get the internet archiving thing right in the first place. It assumes those in power let the multitude of voices be heard. It assumes corporately sponsored sites providing free services for posting content survive, are archived and do the right thing when it comes to preventing censorship.

The Who Built America CD-ROM, released in 1993 and bundled with Apple computers for K-12 educational use, covered the history of America from 1876 and 1914. It came under fire in the Wall Street Journal for including discussions of homosexuality, birth control and abortion. Fast forward to now when schools use filtering software to prevent ‘inappropriate’ material from being viewed by students – in much the same way as Google China uses to filter search results. He shared with us the contrast of the search results from Google Images for ‘Tiananmen square’ vs the search results from Google Images China for ‘Tiananmen square’. Something so simple makes you appreciate the freedoms we often forget here in the US.

It makes me look again at the DOPA (Deleting Online Predators Act) legislation recently passed by the House of Representatives. In the ALA’s analysis of DOPA, they point out all the basics as to why DOPA is a rotten idea. Cool Cat Teacher Blog has a great point by point analysis of What’s Wrong with DOPA. There are many more rants about this all over the net – and I don’t feel the need to add my voice to that throng – but I can’t get it out of my head that DOPA’s being signed into law would be a huge step BACK for freedom of speech and learning and internet innovation in the USA. How crazy is it that at the same time that we are fighting to get enough funding for our archivists, librarians and teachers – we should also have to fight initiatives such as this that would not only make their jobs harder but also siphon away some of those precious resources in order to enforce DOPA?

In the category of good things for historians and educators is the great progress of open source projects of all sorts. When I say Open Source I don’t just mean software – but also the collection and communication of knowledge and experience in many forms. Wikipedia and YouTube are not just fun experiments – but sources of real information. I can only imagine the sorts of insights a researcher might glean from the specific clips of TV shows selected and arranged as music videos by TV show fans (to see what I am talking about, take a look at some of the video’s returned from a search on gilmore girls music video – or the name of your favorite pop TV characters). I would even venture to say that YouTube has found a way to provide a method of responding to TV, perhaps starting down a path away from TV as the ultimate passive one way experience.

Roy talked about ‘Open Sources’ being the ultimate goal – and gave a final plug to fight to increase budgets of institutions that are funding important projects.

Dan’s part of the session addressed that second big idea I listed – using the internet to document major events. He presented an overview of the work of ECHO: Exploring and Collecting History Online. ECHO had been in existence for a year at the time of 9/11 and used 9/11 as a test case for their research to that point. The Hurricane Digital Memory Bank is another project launched by ECHO to document stories of Katrina, Rita and Wilma.

He told us the story behind the creation of the 9/11 digital archive – how they decided they had to do something quickly to collect the experiences of people surrounding the events of September 11th, 2001. They weren’t quite sure what they were doing – if they were making the best choices – but they just went for it. They keep everything. There was no ‘appraisal’ phase to creating this ‘digital archive’. He actually made a point a few minutes into his talk to say he would stop using the word archive, and use the term collection instead, in the interest of not having tomatoes thrown at him by his archivist audience.

The lack of appraisal issue brought a question at the end of the session about where that leaves archivists who believe that appraisal is part of the foundation of archival practice? The answer was that we have the space – so why not keep it all? Dan gave an example of a colleague who had written extensively based on research done using World War II rumors they found in the Library of Congress. These easily could have been discarded as not important – but you never know how information you keep can be used later. He told a story about how they noticed that some people are using the 9/11 digital archive as a place to research teen slang because it has such a deep collection of teen narratives submitted to be part of the archive.

This reminded me a story that Prof. Bruce Ambacher told us during his Archival Principals, Practices and Programs course at UMD. During the design phase for the new National Archives building in College Park, MD, the Electronic Records division was approached to find out how much room they needed for future records. Their answer was none. They believed that the speed at which the space required to store digital data was shrinking was faster than the rate of growth of new records coming into the archive. One of the driving forces behind the strong arguments for the need for appraisal in US archives was born out of the sheer bulk of records that could not possibly be kept. While I know that I am oversimplifying the arguments for and against appraisal (Jenkinson vs Schellenberg, etc) – at the same time it is interesting to take a fresh look at this in the light of removing the challenges of storage.

Dan also addressed some interesting questions about the needs of ‘digital scholarship’. They got zip codes from 60% of the submissions for the 9/11 archive – they hope to increase the accuracy and completeness of GIS information in the hurricane archive by using Google Maps new feature to permit pinpointing latitude and longitude based on an address or intersection. He showed us some interesting analysis made possible by pulling slices of data out of the 9/11 archive and placing it as layers on a Google Map. In the world of mashups, one can see this as an interesting and exciting new avenue for research. I will update this post with links to his promised details to come on his website about how to do this sort of analysis with Google Maps. There will soon be a researchers interface of some kind available at the 9/11 archive (I believe in sync with the 5 year annivarsary of September 11).
Near the end of the session a woman took a moment to thank them for taking the initiative to create the 9/11 archive. She pointed out that much of what is in archives across the US today is the result of individuals choosing to save and collect things they believed to be important. The woman who had originally asked about the place of appraisal in a ‘keep everything digital world’ was clapping and nodding and saying ‘she’s right!’ as the full room applauded.

So – keep it all. Snatch it up before it disappears (there were fun stats like the fact that most blogs remain active for 3 months, most email addresses last about 2 years and inactive Yahoo Groups are deleted after 6 months). There is likely a place for ‘curitorial views’ of the information created by those who evaluate the contents of the archive – but why assume that something isn’t important? I would imagine that as computers become faster and programming becomes smarter – if we keep as much as we can now, we can perhaps automate the sorting it out later with expert systems that follow very detailed rules for creating more organized views of the information for researchers.

This panel had so many interesting themes that crossed over into other panels throughout the conference. The Maine Archivist talking about ‘stopping the bleeding’ of digital data loss in his talk about the Maine GeoArchives. The panel on blogging (that I will write more about in a future post). The RLG Roundtable with presentations from people over at InternetArchive and their talks about archiving everything (ALSO deserves it’s own future post).

I feel guilty for not managing to touch on everything they spoke about – it really was one of the best sessions I attended at the conference. I think that having voices from outside the archival profession represented is both a good reality check and great for the cross-polination of ideas. Roy and Dan have recently published a book titled Digital History: A Guide to Gathering, Preserving, and Presenting the Past on the Web – definitely on my ‘to be read’ list.

Thoughts on Archiving Web Sites

Shortly after my last post, a thread surfaced on the Archives Listserv asking the best way to crawl and record the top few layers of a website. This led to many posts suggesting all sorts of software geared toward this purpose. This post shares some of my thinking on the subject.

Adobe Acrobat can capture a website and convert it into a PDF. As pointed out in the thread above, that would loose the original source HTML – yet there are more issues than that alone. It would also loose any interaction other than links to other pages. It is not clear to me what would happen to a video or flash interface on a site being ‘captured’ by Acrobat. Quoting a lesson for Acrobat7 titled Working with the Web : “Acrobat can download HTML pages, JPEG, PNG, SWF, and GIF graphics (including the last frame of animated GIFs), text files, image maps and form fields. HTML pages can include tables, linkes, frames, background colors, text colors, and forms. Cascading Stylesheets are supported. HTML links are turned into Web links, and HTML forms are turned into PDF forms.”

I looked at a few website HTML capture programs such as Heritrix, Teleport Pro, HTTrack Web and the related ProxyTrack. I hope to take the time to compare each of these options and discover what it does when confronted with something more complicated than HTML, images or cascading style sheets. It also got me thinking about HTML and versions of browsers. It think it safe to say that most people who browse the internet with any regularity have had the experience of viewing a page that just didn’t look right. Not looking right might be anything from strange alignment or odd fonts all the way to a page that is completely illegible. If you are a bit of a geek (like me) you might have gotten clever and tried another browser to see if it looked any better. Sometimes it does – sometimes it doesn’t. Some sites make you install something special (flash or some other type of plugin or local program).

Where does this leave us when archiving websites? A website is much more than just it’s text. If the text were all we worried about I am sure you could crawl and record (or screen scrape) just the text and links and call it a day being fairly confident that text stored as a plain ASCII file (with some special notation for links) would continue to be readable even if browsers disappeared from the world. While keeping the words is useful, it also looses a lot of the intended meaning. Have you read full text journal articles online that don’t have the images? I have – and I hate it. I am a very visually oriented person. It doesn’t help me to know there WAS a diagram after the 3rd paragraph if I can’t actually see it. Keeping all the information on a webpage is clearly important. The full range of content (all the audio, video, images and text on a page) is important to viewing the information in its original context.

Archivists who work with non-print media records that require equipment for access are already in the practice of saving old machines hoping to ensure access to their film, video and audio records. I know there are recommendations for retaining older computers and software to ensure access to data ‘trapped’ in ‘dead’ programs (I will define a dead program here as one which is no longer sold, supported or upgraded – often one that is only guaranteed to run on a dead operating system). My fear is for the websites that ran beautifully on specific old browsers. Are we keeping copies of old browsers? Will the old browsers even run on newer operating systems? The internet and its content is constantly changing – even just keeping the HTML may not be enough. What about those plugins – what about the streaming video or audio. Do the crawlers pull and store that data as well?

One of the most interesting things about reading old newspapers can be the ads. What was being advertised at the time? How much was the sale price for laundry detergent in 1948? With the internet customizing itself to individuals or simply generating random ads how would that sort of snapshot of products and prices be captured? I wonder if there is a place for advertising statistics as archival records. What google ads were most popular on a specific day? Google already has interesting graphs to show the correspondence between specific keyword searches and news stories that google perceives as related to the event. The Internet Archive (IA) could be another interesting source for statistical analysis of advertising for those sites that permit crawling.

What about customization? Only I (or someone looking over my shoulder) can see my MyYahoo page. And it changes each time I view it. It is a conglomeration of the latest travel discounts, my favorite comics, what is on my favorite TV and cable channels tonight, the headlines of the newspapers/blogs I follow and a snapshot of my stock portfolio. Take even a corporate portal inside an intranet. Often a slightly less moving target – but still customizable to the individual. Is there a practical way to archive these customized pages – even if only for a specific user of interest? Would it be worthwhile to be archiving the personalized portal pages of an ‘important’ or ‘interesting’ person on a daily basis – such that their ‘view’ of the world via a customized portal could be examined by researchers later?

A wealth of information can be found on the website for the Joint Workshop on Future-proofing Institutional Websites from January 2006. The one thing most of these presentations agree upon is that ‘future-proofing’ is something that institutions should think about at the time of website design and creation. Standards for creating future-proof websites directs website creators to use and validate against open standards. Preservation Strategies for institutional website content shows insight into NARA‘s approach for archiving US government sites, the results of which can be viewed at http://www.webharvest.gov/. A summary of the issues they found can be read in the tidy 11 page web harvesting survey.

I definitely have more work ahead of me to read through all the information available from the International Internet Preservation Consortium and the National Library of Australia’s Preserving Access to Digital Information (PADI). More posts on this topic as I have time to read through their rich resources.

All around, a lot to think about. Interesting challenges for researchers in the future. The choices archivists face today often will depend on the type of site they are archiving. Best practices are evolving both for ‘future-proofing’ sites and for harvesting sites for archiving. Unfortunately, not everyone building a website that may be worth archiving is particularly concerned with validating their sites against open standards. Institutions that KNOW that they want to archive their sites are definitely a step ahead. They can make choices in their design and development to ensure success in archiving at a later date. It is the wild west fringe of the internet that are likely to present the greatest challenge for archivists and researchers.
