I strongly suggest that you read the copyright the ACM put on that
article.  It says

   Permission is granted to copy wihtout fee all or part of 
   this material provided that the copies are not made or
   distributed for direct commercial advantage ... [stuff
   about preserving the copyright] ... To copy otherwise
   requires a fee and/or specific permission.

Or something close to that.  I'm going by more recent ACM
copyright notices.

Note that this is quite different from the usual copyright put on
books and I have always regarded it as a strong point in favor of
the ACM.
