Where Did the Web Archive Go?

Abstract:  To perform a longitudinal investigation of web archives and detecting variations and changes replaying individual archived pages, or mementos, we created a sample of 16,627 mementos from 17 public web archives. Over the course of our 14-month study (November, 2017 – January, 2019), we found that four web archives changed their base URIs and did not leave a machine-readable method of locating their new base URIs, necessitating manual rediscovery. Of the 1,981 mementos in our sample from these four web archives, 537 were impacted: 517 mementos were rediscovered but with changes in their time of archiving (or Memento-Datetime), HTTP status code, or the string comprising their original URI (or URI-R), and 20 of the mementos could not be found at all.

“We’re hiring an outreach and support coordinator to help us meet the exploding need for library-powered open educational resources and web archiving tools.

You’ll take the lead in sharing and supporting H2O, our platform for open legal textbooks and other resources. You’ll be the main point of contact for faculty using H2O at Harvard, and you’ll be deeply involved in our efforts to work with colleagues at other schools and libraries to support widespread use of H2O. You’ll also be working closely, in an editorial capacity, with a small number of faculty authors preparing print versions of their open textbooks.

In addition to your work on H2O, you’ll be an important part of the team working to support Perma.cc, our web archiving service, and to adapt it to critical new use cases, such as fact-checking and journalism….”
