Through the Canadian Resource Knowledge Network (CRKN), the library participates in a number of agreements with publishers that either provide discounts on article publication charges (APCs) for open access (OA) articles, or that waive the APC entirely.
The SciFree journal search tool lists journals that fall under these agreements.
You can also find journals in the Directory of Open Access Journals (DOAJ) that do not charge an APC and follow best practices in open access publishing.
