Open access (OA) is becoming a reality, with new cost models under development. The various cost models will have serious short- and long-term implications for libraries and dangerously impact the scholarly communication network. I believe that the adoption of the OA model for journals will create serious instabilities within the existing scholarly publication industry. OA, as a business model, is neither necessary nor desirable. With or without the often-discussed author charges approach, it would be almost impossible to obtain the same amount of total revenue through selected libraries as now exists from the much larger base of library subscriptions. Tiered or differential pricing (and services) among the existing subscribers would be a far more logical approach to supporting a modified scholarly journal distribution network.
