UA Libraries negotiated a Read and Publish agreement with Cambridge University Press allowing newly-published articles by UA researchers to be published Open Access in any of nearly 400 Cambridge University Press journals -- all at no cost to the authors. The agreement represents a significant breakthrough in bringing UA's leading-edge research to readers without restrictive paywalls or extra charges, and in helping to build a new, more financially-sustainable model of scholarly communication.
