It’s a beautiful business to be in: publish research that you took no part in, claim the copyrights to the results of that research, publish the research in a very expensive journal, publish reprints at exorbitant fees and finally, when a more efficient distribution method appears get rid of all the costly components of the business but keep the prices the same. According to one person I spoke to who is knowledgeable about the publishing field the profit margins dwarf even those of the publication of pornography.
