How is the information in newspapers currently preserved which is permanent and accessible (otherwise why archive at all) that a series of articles on the web could not also be preserved? This is meant as an honest question as I remember microfiche and microfilm as the primary methods for preserving newspaper content. I assumed they were largely replaced with digital subscription based archives like lexus-nexus. And a digital archive can probably archive already digital information at least as easily as non-digital. I know that libraries often keep physical newspapers like 5 or so years back but even after 5 years due to the quality of paper, ink, air, and occasional use. They are getting brittle and unable to be handled. News papers in their normal form were never intended to be permanent, hence why they were (are?) stored on microfilm or other archival methods.
