Abstract
The discussion on the transformation of scholarly journals to open access (OA) increasingly concerns financial aspects. Considering the variety of funding strategies for article processing charge (APCs), the array of cost types for scientific information and the need for data monitoring to promote cost transparency, an integrated view of the financial dimension of the OA transition is needed. This commentary describes the need for implementing an information budget that looks beyond just the library budget and comprehensively targets all financial flows from universities and other research performing organizations to publishers. An information budget promotes an integrated perspective on the distributed costs at a given institution. This centralized approach of assessing financial flows can be used to strengthen the position of research institutions when negotiating with publishers.
