I wonder about the provenance of those files.  Looks like user eknikko is just uploading texts to the Internet Archive without any cooperation from the authors&#x2F;publishers.  His or her channel[1] includes copies of K&amp;R, Stroustrup&#x27;s C++ book, and Intro to Algorithms by Cormen et al, among other things.<p>I know the Archive doesn&#x27;t have the strictest policy on copyright (tons of old commercials, magazine scans, and other ephemera that most people see as a grey area is available), but I doubt even their views are lax enough to look at this as kosher.<p>1. <a href="https:&#x2F;&#x2F;archive.org&#x2F;details&#x2F;@eknikko" rel="nofollow">https:&#x2F;&#x2F;archive.org&#x2F;details&#x2F;@eknikko</a>
