All PGRI articles are published online with immediate, free access for readers worldwide. PGRI does not use subscription barriers or embargo periods.
Free article processing charge
PGRI operates a Free APC model. Authors are not charged submission, publication, page, colour, or article-processing fees. The publishing process is supported by World Bridge Knowledge Hub as part of its commitment to open scholarly communication.
Copyright and licensing

What open access supports
