What a bunch of lame BS excuses.<p>Searching for &quot;Computer Programming as an Art&quot; the PDF comes up as the second link (below PG&#x27;s rip off).  Not that it&#x27;s even relevant because it&#x27;s given as a direct link.<p>A scanned PDF is a closer reproduction to the original presentation, and easier to save for later to read.<p>I trust the ACM&#x27;s &quot;goodwill&quot; to continue hosting it more than I trust it to remain on PG&#x27;s website.
