Thanks! The main page (http://readscheme.org/) has a contact address for the maintainer; maybe they'll add those links to the site if you let them know.
...or result in a takedown. The links appeared on the first page of Google searches for the title. And the ACM appears pretty committed to monetizing articles in PDF format.
I don't get it. Are you suggesting one can't link to a paper on a completely legit MIT site, because a version of the paper was later published in an ACM publication?
No. I am stating that the copyright status of the files sitting at the end of my links is unknown. They may be hosted legally with the rights holder's permission. They may be hosted legally under fair use.
On the other hand, general access could exceed fair use - e.g. the hosted copy was made for archival purposes of a licensee. Or the hosted file could simply be an illegal copy. While hosting at MIT has some correlation with legitimacy in this particular case, it in no way insures it.
Right now, the papers are there for anyone with a web connection. The risk of breaking that far outweighs the benefits of fixing readscheme.
