web-archive
Vefsafn.is (Icelandic Web Archive)
Iceland's national web archive, run by the National and University Library, which has harvested the entire .is domain about three times a year since 2004 and holds Iceland-related sites back to 1996. Snapshot lists come from its Memento timemap, and individual captures open as replay links on vefsafn.is, where the viewer may ask you to pass a CAPTCHA. The natural source for the history of Icelandic websites.
Why it’s useful & how it works
FINDING: replay HTML is behind hCaptcha (403) both ways, but the Memento TimeMap returns 200 both ways. Same pattern as archive.today — integrate via TimeMap for existence, hand a direct replay link to the user.
What’s inside
Full .is harvested ~3x/year since 2004; tens of TB+.
API access
