Portico now hosts the content from four additional journals: Open Material Sciences, Biofuels Engineering, and Waste Treatment and Recovery, all published by De Gruyter, and Journal of Innovation in Health Informatics, published by BCS Learning and Development.

These titles are no longer available through their publisher or a successor; therefore, they have “triggered” and are freely available to the community via the Portico archive. These titles were all originally published as Open Access, and will remain Open Access through Portico.
