Dear Readers

Thank you for visiting my collection of digital preservation concepts!

As you have probably guessed, I am no longer updating this blog, but I sincerely hope that it continues to serve as a resource for the basic concepts and processes that make up this (no-longer) nascent field. I’d imagine that some of these writings are no longer up-to-date, as is the inevitable nature of anything that tries to capture a digitally-focused moment in time.
The constant changes in our digital environments are exciting and call for consistent adaptation. Since leaving grad school, I have moved on to roles in the tech industry, and have learned this: Despite the institution or industry, I think that the challenge of ‘keeping up’ is exhilarating, pervasive, and always involves a gamble. In particular, digital preservation is not for the faint of heart! I applaud the passion and competency with which this field has grown to approach the preservation of valuable digital resources. Please feel free to reach out for anything.


Digitization Specifications Compilation

Really briefly, I wanted to direct you to the new page I added to this blog, Digitization Specs. Currently there is a compilation of various specs for digitizing photographic prints and negatives.

Just for fun (and reference) I compiled the photograph digitization specifications that I could locate from the websites and publications of various libraries and cultural heritage institutions.  I thought it would be neat to see them all side by side, and as far as I know, there isn’t such a resource yet.  I’ve included specifications for color and black & white photos, in print and film form.

I also intend to eventually compile specifications for digitizing text/print-based documents, but that’s for another day!

A Budding Branch?

This evening I sat in on a lecture given by John Phillips, a Management Consultant at Information Technology Decisions.  John was giving an overview of what he saw as the similarities and differences between the three main branches of information management professionals: librarians, archivists, and records managers.  What was not included in this list were digital preservationists.

Now, as someone who is not actually working in the field, I may be remiss in assuming that digital preservation has yet earned thusly titled professionals.  But I think if this is not yet the case, then it certainly will be in the future…once it becomes clear that professionals from the other three branches of information management cannot be expected to all have expert-level knowledge of digital preservation practices….which will become clear because everyone in information management really needs to starting thinking about technological obsolescence.

The point of this post, though, is to point out a major correlation between records managers and what I would be inclined to think of as digital record preservationists.  As John pointed out, records managers differ from librarians and archivists because, 1) they tend to work in business or corporate environments, and 2) they are OK with – and are expected to – throw things away after they are no longer of value to the owning organization.

Upon an item’s accession into a repository, records managers will asses the value of an object, and then revisit that assessment later on in the course of retention decisions.  If the item is no longer worth keeping, it is discarded.  This is also the (theoretical) case with digital preservationists.  In digital preservation, OAIS-type repositories are intended to preserve digital items for as long as those items are of value to their designated communities.  This implies that at some point, a digital item may no longer have value, and therefore continued preservation efforts for that item are not economically justified.  Throwing things away is a dirty job, but just as we can’t possibly collect everything out there, perhaps we can’t keep it all, either.

But let’s not discredit those clingy librarians.  John gave an interesting guesstimate regarding the types of respective repositories information professionals work with.  Among records managers, archivists, and librarians, librarians deal with the highest proportion of electronic to physical records out of all three professions.  (John’s guesstimate was 40% electronic / 60% physical, in comparison to IT professionals, who are 100% electronic by nature.)  The numbers for records managers were 30% electronic / 70% physical, which is still quite a lot of paper to be dealing with.
So if librarians are handling the highest proportions of electronic items out of these three groups, we can make a big case for libraries to be the battle grounds for creating leaders in digital preservation.  Technological and file format obsolescence will hit libraries the hardest if these numbers are accurate.  As contenders with the most to lose, libraries are poised to harbor the most institutional support for digital preservation initiatives…and perhaps spawn the fourth major branch of information professionals.


Welcome to my new blog location!  I have moved to WordPress, and I’ll bring over some of my key posts from my previous blog host soon.

This blog is intended to provide basic information about concepts, organizations, people, methods, and breakthroughs in the field of digital preservation.  Closely tied to digital preservation efforts are digital repositories, so you will see posts about them as well.  Please use the search function or the Post Tags and Categories to look for something specific…or to just browse around.

Thanks for stopping by!
