Open access resources are research/study materials have been made available to the general public, free of charge: data and datasets, books and articles, including scholarly research articles. This is not the same thing as public domain works, or those items that have fallen out of copyright protection; open access authors have chosen to share freely, so anyone can use the works legally without permission or fees.
