That's the problem. The audience is focused on nature and science publications...
Our journal club only has high impact publications because "we want to get to that standard" but there are so many good plosone publications etc.
Do you know how much a university pays for access to all nature journals for example? Would be interesting to know.
My uni has access to some nature journals, but funnily, not to Nat. Communications where we have published ourselves (!!!)
So I end up using libgen or /r/scholar
