It is obvious from nearly all responses to my recent question that researchers do not like paying the exorbitant amount currently being charged for OA journal publications by most publishers. On the other hand, publishers claim that there is a cost that must be met in providing OA to journals free of charge. If, in future, researchers are required to pay, how much will you willingly pay? Will the IF of the journal influence how much you are willing to pay? Or would you give up publishing in journals charging fees for OA all together?
