PDFs:
1) That's a browser plugin. It works in Firefox, and possibly other browsers, but not all. Eg. this PDF link opens in-browser in Firefox, but not in Chromium: https://en.wikipedia.org/wiki/Scrabble#cite_note-4

2) Not all PDF links work even in Firefox, eg: https://en.wikipedia.org/wiki/Scrabble#cite_note-12

Deadlinks:
Very interesting. Thanks Nemo, for letting us know. I've added links to that page at Enwiki, and viceversa.

Conceptually I agrees, somewhat… but partly not. on wiki pdfs aren't
downloaded they're viewed on an in-page viewer, its basically not a PDF
at that point, so i don't get the value of classifying the links for them.

Broken links should be fixed, but in the case where they can't the
internet archive things sounds pretty interesting.

    Also, the Internet Archive brought up a proposal to "Create a visual
