In anticipation of the Museum Computer Network conference next week in Seattle, I’ve been giving some extra thought lately to museum community involvement in digital preservation. We (the National Digital Information Infrastructure and Preservation Program, that is) work with many partners from a range of industries, and in the last couple of years this has …
Kent Anderson offers a provocative post in The Mirage of Fixity — Selling an Idea Before Understanding the Concept. Anderson takes Nicholas Carr to task for an article in the Wall Street Journal bemoaning the death of textual fixity. Here’s a quote from Carr: Once digitized, a page of words loses its fixity. It can change …
The following is a guest post by Nicholas Taylor, Information Technology Specialist for the Repository Development Group at the Library of Congress. Prompted by questions from Library of Congress staff on how to more effectively use web archives to answer research questions, I recently gave a presentation on “Using Wayback Machine for Research” (PDF). I …
Fixity is a key concept for digital preservation, a cornerstone even. As we’ve explained before, digital objects have a somewhat curious nature. Encoded in bits, you need to check to make sure that a given digital object is actually the same thing you started with. Thankfully, we have the ability to compute checksums, or cryptographic hashes. This …
Here at the Library of Congress, there are many projects underway to digitize and make available vast amounts of historic, archival material. One such project is the National Digital Newspaper Program, providing access to millions of pages from historic newspapers (a previous blog post provides an introduction). Deb Thomas, NDNP program coordinator here at the …

The talk covered a wide range of topics–his love of books as physical objects and his background working in libraries and …
Today’s guest post is by Carlos Martinez III, a Hispanic Association of Colleges and Universities intern in the Library of Congress’s Office of Strategic Initiatives. The National Information Standards Organization provides standards to help libraries, developers and publishers work together. Their report, A Framework Guidance for Building Good Digital Collections, is still as helpful to organizations today …
I bought a new computer this summer. I immediately copied all of my digital files from my old computer to my new one and to an external hard drive. Now I had three copies of my digital content on three different devices. Because if something happens to one of those media, I’ve got two others …
A question popped up in the blogosphere recently. “Where is our Atlas of Digital Damages?” asked Barbara Sierman of the National Library of the Netherlands. She pointed out the amazement that would greet evidence of physical books, safely stored, with spontaneous and glaring changes in their content or appearance. “Panic would be huge if this …
As digital preservation and stewardship professionals, we approach digital objects from a unique perspective. We evaluate the long-term value of any particular digital object and work to develop a technical and social infrastructure that will enable us to successfully preserve the objects over time. Preserving and providing appropriate access are our primary functions, but no …
