However the term "public domain" is often mis-used to mean "freely available but under copyright", in which case he (or the publisher) retains full legal control over any copying (a.k.a. distribution). So perhaps counter-intuitively, just because it's freely available online doesn't mean it can be re-posted without infringement. Linking to his site or obtaining permission to host it are the only safe ways to handle it.
