These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
This is a collection of web page captures from links added to, or changed on, Wikipedia pages. The idea is to bring a reliability to Wikipedia outlinks so that if the pages referenced by Wikipedia articles are changed, or go away, a reader can permanently find what was originally referred to.
Trent Reznor and NIN art director John Crawford set out to make the “definitive editions” of all the main NIN releases on vinyl. Reznor: “We want to present the catalog as it was intended to be, with no compromises. That means a careful remastering of the audio from the original sources, a careful and painstaking recreation of the artwork, pristine materials, some surprises and an insane attention to detail that you probably won’t notice… but it matters to us. No extra bullshit and gimmicks – the “real” records in their truest form available at a reasonable price.”
