Why do you bring up university presses? No one else singled them out. Usually when people do, it is as the baseline reasonable journal cost, an order of magnitude less than commercial presses. In this context, of single articles, they use the same pricing as commercial presses, but that's probably incompetence on both parts.

Razib Khan found this paragraph rather striking (who is reminded of this episode of South Park) and I would tend to agree that its a rather convincing argument.
Are publishers really so successful as rent seekers or is there something the original article is missing here? Also what useful strategies would LWers recommend to help minimize costs for someone trying to practice the virtue of scholarship? The obvious suggestions (implied in the article) seem to be emailing authors (and perhaps those suscribed) asking for the papers and acquiring and paying for membership in some libraries.
Another obvious option is using ... liberated databases of such academic papers.
Edit: Just wondering, has this been discussed before on Lesswrong?
