The PDF URLs for
bstj.bell-labs.com no longer work,
and the ones for
www.alcatel-lucent.com ... now redirect to an HTML page.
With any luck, someone scraped them before they went.
I've gotten in the habit of scraping all the Web content I look at, since it
has (as above) a distressing tendency to vapourize.
