From 4 October 2023, Theory and Practice of Logic Programming will be moving to a Gold Open Access publishing model. All accepted articles from this date will be published with a Creative Commons licence and will be subject to an Article Processing Charge (see the journal’s Open Access Options page for available licence options). Many corresponding authors will have their APC covered by a transformative agreement; check here to see if your institution is covered. Any author without funding or not covered by a transformative agreement can apply for a waiver.
Please see the journals Open Access Options page for instructions on how to request an APC wavier.
