I can not recall the book, but one of Isaac Asimov's novels ends with an article on muon-catalyzed fusion. I remember that because it was so impressive to find out that such a thing was real.
I've also seen a few other authors acknowledge the origin of the ideas they are promoting in an acknowledgements section at the end of the book.
What is the right way to make acknowledgements or reposting articles?
For reposting articles, I'd think at a minimum that I need to ask the original publication for permission (and maybe the author).
What is the right to make acknowledgements? Should I write someone asking for their permission before including them?
