Notes de l'éditeur

  • Checklist, https://www.flickr.com/photos/adesigna/4090782772
  • First of all, why is web archiving important?
    As members of memory institutions, it is the continuation in a new technological context of our longstanding mission and obligation to collect, preserve, and provide access to the scholar record and our collective cultural heritage.
    Since the web is where the content is, that is where we have to go to acquire it.
    But the fundamental problem is that the web is not web.
    As soon as you think you have quantified or characterized it, it has changed into something else; and as soon as you have processes in place to capture web content, the content is not available in the same way.

  • It’s different than what anyone – Tim Berners-Lee included – had in mind 25 years ago
    The web is no longer giant document retrieval system, but a programming environment
    The browser is no longer a document view, but a general purpose virtual machine; its fundamental language is no longer HTML but JavaScript.
    The mode of experience has shifted from a common to a highly personalized one; whose web are we archiving?

  • Paywalls, robot exclusions, crawler traps, … What we need is a collection mechanism that acts like a person

    How to find enough good people? (We’re hiring!)
  • “You’re collecting that?”
    May need programmatic or API access to in situ collection analysis
  • Headless browsers (PhantomJS, Umbra, etc.), API harvesters
    Make browsing the past web as simple and intuitive as browsing the live web

  • Avoid needless duplication of effort
    As librarians we have historically given perhaps inordinate priority to content creators and curators and not enough to consumers. But over significant timespans it is the users who affirmatively seek out and exploit content who may be best positioned to contribute towards its successful management.
