Article processing charges: a five-year price trajectory
Authors
Abstract
List prices rose faster than inflation in every discipline surveyed, with the steepest increases at the most selective titles. The analysis draws on a corpus assembled from institutional repositories, preprint servers and publisher metadata feeds, and the full dataset together with the code needed to reproduce every figure is deposited under a permissive licence. Limitations, including coverage gaps in non-English sources, are set out in the discussion.
