And, “Who pays” is not answered by pointing out aspects of the peer review structure. It is properly answered by identifying who buys, or otherwise subsidizes, the journal (not the reprints).
I assume you know that most scientific journals have a hefty subscription fee, reduced by only a few dollars by membership in the associated scientific society. Additional funds are raised by scientific conferences held once a year or every two years that require a registration fee for professionals attending and a similar fee for conference exhibitors. Sometimes a conference will have multiple sponsors so as to attract a maximum number of registrants and split the costs accordingly. And I have both published and presented papers in my professional career, beginning in college, though I am not now associated with a university or research institution.
The subscription fees for top scientific journals are way beyond my means anymore. Fortunately a university with apparently unlimited library funding is just three miles up the road.
Maybe they did’t like how he parted his hair.
You are aware, are you not, that there is no obligation to hire any specific individual?
As for publishing, as you have just pointed out, subscriptions cost an arm and a leg. Do you think the libraries and universities would pay as much for non-peer reviewed journals?
