MDPI, the Open Access (OA) publisher, today announced more than 1,000 partners have joined its Institutional Open Access Program (IOAP), a significant milestone for the organization. The agreements span 59 countries, covering North and South America, Europe, Asia, Africa, and Oceania.

Last year alone, more than 150 new libraries and academic institutions joined MDPI’s IOAP. The expansion of an existing consortium deal in Sweden added a further 75 partners to the publisher’s portfolio in January 2026, enabling MDPI to surpass the 1,000-partners milestone.

The IOAP supports affiliated researchers by streamlining submission processes, reducing administrative burdens, and offering discounted Article Processing Charges (APCs). Through IOAP membership, more than 61,300 research articles received APC discounts last year alone, driving greater visibility and accessibility for partner institutions and global research communities alike.

“This milestone marks a significant step towards expanding MDPI’s global impact,” said Stefan Tochev, MDPI CEO. “Reaching 1,000 IOAP partnerships is a true testament to the growing trust and collaboration we’ve built with universities, libraries, and research organizations worldwide. We are proud to lead the way in Open Access publishing, ensuring researchers have the support they need to reach global audiences.”

“The success of our program is reflected in the growing global demand for Open Science and quality publishing services,” said Becky Castellon, MDPI institutional partnerships manager. “Equally, institutions are increasingly seeking Open Access publishing options that support funder and national mandates. Joining the IOAP makes compliance simple.”
