The Digital-Surrogate Seal of Approval
[Update: The article is also available in the Stanford Digital Repository and the University of California Escholarship Repository.] James and I are happy to announce that our new article appears in the current edition of D-Lib Magazine:
- The Digital-Surrogate Seal of Approval: a Consumer-oriented Standard. by James A. Jacobs and James R. Jacobs. D-Lib Magazine, 2013, 19(3/4). DOI: http://dx.doi.org/10.1045/march2013-jacobs
When bits go bad: the Atlas of Digital Damages
Ever heard the term "bit rot" or wondered what actually happens when electronic files go bad? The Atlas of Digital Damages is a collection of files with corrupted bits, so you can visually see what happens. The Atlas is a flickr album, or rather "a staging area for collecting visual examples of digital preservation challenges, failed renderings, encoding damage, corrupt data, and visual evidence documenting #FAILs of any stripe." So, in addition to viewing these examples, you too can contribute examples to help build the Atlas' collection. A blog post by Barbara Sierman, from the National Library of the Netherlands, first posed the question and well, folks ran with the idea and created this "crowd sourced effort" to document digital degradation. See, "Where is our atlas of digital damages?".
I discovered this nifty item while reading through the November Digital Preservation Newsletter from the Library of Congress (there's lots of great project updates and information, especially on the geospatial digital preservation front in there - so go check it out!)
and check out the LOCKSS project for digital preservation approaches and methods to prevent bit rot on a large scale.

Accuracy of Digitization
The Update on February 2012 Activities of the HathiTrust reports on research being done by the HathiTrust Research Center (HTRC) to quantify occurrences of Optical Character Recognition (OCR) errors in the HathiTrust corpus. OCR is the technology that converts a scanned image to text that can be searched and analyzed. Members of the HTRC examined 256,000 non-Google digitized volumes from HathiTrust using a clever algorithm that compared OCR text to a dictionary of known words. Using a supercomputer and a set of rules that were verified by a human expert, they found that 84.9 percent of the volumes examined (217,754 of the 256,416) had one or more OCR errors and 11% of the pages (7,745,034 of the 69,297,000) had one or more errors. The average number of errors per volume was 156. As we at FGI have argued here before, we believe that it essential to take into account OCR accuracy and error rates when digitizing paper collections. This is particularly important when digitizing books that contain statistical tables since it is harder to use current OCR technologies to accurately convert image scans to numbers than it is to convert scans to text. It is also harder to evaluate the accuracy of such conversions; you can't use a dictionary of known statistics the way you can use a dictionary of known words. (The HTRC study did not, apparently, examine accuracy of statistical table conversions.) Because of the large volume of such information in government publications, this is a very important issue as we collectively try to digitize our paper collections, evaluate their accuracy and usability, and determine how many paper copies we need to keep after digitization (see Achieving a collaborative FDLP future).

AOTUS responds to petition to create federal scanning commission
Earlier this month, we posted about the "Open letter and petition to President Obama to create a federal scanning commission and digitize all .gov publications". The petition closed on 1/20 and now David Ferriero, the Archivist of the US at the National Archives, has given the official NARA response. I'd say this is a positive first step, but much discussion is still needed. Please join the conversation over at the NARA Blog. I think documents librarians will be invaluable to this effort going forward!
Digitizing Federal Public Records By David Ferriero Thank you for signing a petition asking the Obama Administration to digitize all public records. The Obama Administration believes increasing access to our collections by digitizing our records is a great idea. Our most recent efforts to do this ourselves as part of our OpenGov initiative, include the Citizen Archivist project, a Wikipedian in Residence, Tag it Tuesdays, and Scanathons. We are also moving forward on implementing the President’s recent Memorandum on Managing Government Records, which focuses on the need to update policies and practices for the digital age. But all those things aren’t enough. Your petition, and the Yes We Scan effort broadly, calls for a national strategy, and even a Federal Scanning Commission, to figure out what it would take to digitize the holdings of many federal entities, from the Library of Congress to the Government Printing Office to the Smithsonian Institution. These ideas bring up a host of questions that still need to be answered: What should the National Archives’ priorities be? Do we focus on preserving deteriorating paper records, still bound with red ribbons from two centuries ago? Do we make digital copies of Vietnam Era film footage? Should we focus on preserving those older paper records while citizens volunteer to digitize more recent, and better preserved, records? The National Archives – which houses the Nation’s permanent records – is looking for your input to help answer these important questions on how we move forward. What are your thoughts on how the National Archives and other agencies should proceed? What questions should we be asking ourselves? You can add your thoughts over on the National Archives blog, and I’m looking forward to having a longer discussion with the creators and signers of this petition on this important issue in the coming weeks– more details on that will follow. Thank you again for your interest in this important issue. I’m looking forward to your ideas on how we can proceed with digitizing federal public records.

Digitization does not magically preserve paper
May 30, 2012 / Leave a comment
When we think about the historical paper-and-ink collections that FDLP libraries have built over the last 200 years, we often wish we could make them more accessible through digitization. But we have to be careful when we think this way. One thing I have learned repeatedly as I have worked with digital information over the last twenty five years is that, in the digital world, "access" and "preservation" have to go together. When we neglect either, we lose both. Some recent writings have reinforced this old idea and are worth remembering:
- All Digital Objects are Born Digital Objects, by Trevor Owens, The Signal (May 15th, 2012).
There is no large red button that says "digitize" on it, we make decisions about what significant properties we want to record from a physical object and we work to ensure that those properties are recorded in the newly created digital object. When we talk about the scanner "digitizing" it's all too easy to forget the history of the creation of the digital object and we can easily forget that there are a range of individual and institutional authorial intentions that go into deciding what and how to digitize.
- Digitization is Different than Digital Preservation: Help Prevent Digital Orphans!, by Kristin Snawder, The Signal (July 15th, 2011).
Many institutions see the immediate value of having materials available electronically. This is valid reasoning. Many researchers no longer want to come and see the materials. They want access from the comfort of their own couch and fuzzy slippers. But, in the hurry to meet user expectations, institutions may scan large quantities of materials without having a solid plan for preserving the digital images into the future.

Approaching Digitisation Through A Digital Preservation Perspective. by Alenka Kavčič-Čolić. Presented at the SEEDI (South-Eastern European Digitisation Initiative) 2012, Ljubljana, Slovenia.
Most libraries still conceive digitisation as a digital reproduction aimed to provide access to library materials only. The master files resulted from digitisation are usually not digitally preserved and the digital collections run the risk of being lost for the future.
The above examples are about short-term thinking and lack of planning when libraries aim for access without planning for preservation. The same mistake can be made the other way, too: when libraries plan for preservation without access. Paul Conway made this point more than 15 years ago: Continue reading →Continue Reading →
