My original message talked about two topics: open choice successclauses, and subscription to open access transition. One thought in this message is the possibility of a gradualtransition from subscription to open access, through librarybased payments that are a combination of subscription payments,and open access processing fee payments. For the avoidance ofdoubt, I am specifically talking about fees to make articles openaccess, not the traditional page charges that have been paid byacademic departments in the print / subscription environment. In order for this to work, the library must be able to deduct theOA processing fees paid from subscriptions. This is most likelyto succeed when the library coordinates payment of OA processingfees. This approach to transition is most obvious with the "openchoice" publishing option. This might work really well if publishers decrease subscriptioncosts for everyone when anyone pays OA processing fees.However, there are a number of advantages to having the librarieswhich pay the fees receive the discount. First, there is muchmore incentive with this approach for libraries to participate;it is also fairer. Second, there are a number of efficiencyadvantages. For example, there are invoicing efficiencies forthe publishers, an excellent bargaining point for the libraries.That is, by doing the work of coordinating the payments,libraries are in a good position to negotiate a reduced OAprocessing fee rate for their faculty, in addition to reducedsubscription costs. Kudos to Jan Velterop and Springer for beginning to discusstransition from full subscription payments to a combination ofsubscription / open choice with libraries and consortia. [Note:this is not an endorsement of the Springer Open Choice option]. While this process is most obvious with open choice, the samebasic principles can be used to transition from subscriptions ingeneral to support for fully open access journals.
