Article processing charges (APCs) are fees paid to the publisher by or on behalf of the author, in exchange for publishing the article on an open access basis: without a paywall and (typically) with an open license such as one of the Creative Commons licenses. Libraries sometimes make agreements with publishers that cover or discount APCs for articles that have an author affiliated with their institution. These agreements can be called "read and publish agreements" or "transformative agreements." See below for a list of Penn State's agreements of this type.
The following APC discounts are available to Penn State authors. Most of the discounts listed below are complete discounts resulting from "read and publish" or "transformative" agreements. Some partial discounts are also listed.
