Here’s an updated, citation‑rich article exploring how IOP (Institute of Physics & IOP Publishing) is leading the charge to open up physics journal publishing.
1. A Legacy Rooted in Openness 🌐
IOP Publishing launched the first fully open‑access general physics journal—New Journal of Physics (NJP)—in collaboration with the Deutsche Physikalische Gesellschaft in 1998. Since then, it has continued to pioneer open-access physics publishing . NJP remains fully open access under a CC BY license .
2. The Open Physics Programme: Principles in Action
Launched in 2020, Open Physics reflects IOP Publishing’s strategic commitment to openness across three pillars:
• Access: widening researcher reach by offering open access options across all its journals.
• Transparency: implementing transparent and optionally open peer review, transparent metrics and editorial reporting.
• Inclusivity: increasing geographic, gender and institutional diversity across authors and reviewers .
By 2025, IOP had made transparent peer review standard on all hybrid journals, and was assigning DOIs to supplementary data files, supporting FAIR data sharing – a notable step in openness .
3. Scaling Open Access: Progress & Transformative Agreements
➤ Growth in OA Content
• In 2022, 41% of IOP journal output was OA—up from 26% in 2021.
• By 2024, this rose to 47%, representing nearly half of all published articles .
➤ Transformative Agreements
• IOP has signed “read-and-publish” (transformative) agreements with hundreds of institutions across 28 countries by 2023, and expanded to 900 institutions in 33 countries.
• These agreements allow authors at participating institutes to publish papers OA without paying separate author fees .
➤ APC Waivers & Discounts
• IOP offers waivers or discounts on article publication charges for authors from lower‑income countries, with full waivers for Group A countries and 50% discounts for Group B .
4. Domain-Specific Open Access Initiatives
SCOAP³ & Particle Physics
IOPP participates in SCOAP³, an international consortium converting leading high-energy physics journals to fully open access, with author-retained CC BY licensing. NJP, Chinese Physics C and JCAP are among the participant journals .
Journal Launches and Model Flips
• New journal launches include diamond OA and gold‑OA titles (e.g. AI for Science, Journal of Reliability Science and Engineering) with no fees for authors .
• Key publications flipped fully to OA: Applied Physics Express in 2024; Nuclear Fusion in 2023 .
5. Data Sharing & Research Integrity
• Since 2022, IOP has required data availability statements in all articles, and in 2023 mandated explanations if data aren’t shared .
• In 2025, it extended a stronger data-sharing policy to environmental research journals and began assigning DOIs to supplementary data to improve discoverability and FAIR compliance .
6. Leadership in Physics Scholarly Culture
• In March 2025, IOP joined with AIP Publishing and the American Physical Society under the Purpose‑Led Publishing coalition, renewing the commitment to “science first,” and access without compromise on integrity .
• In December 2020, IOP was a key signatory to a joint statement by major physics societies supporting open access, arguing for sustainable models with hybrid and transformative agreements .
7. Real‑World Impact & Outlook
• In 2022, 66% of articles included data‑availability statements, signalling a cultural shift toward transparency .
• Average time from submission to acceptance: ~95 days; from acceptance to online publication: ~18 days .
• New journal titles and series in areas like machine learning, climate/environmental research, and AI reflect high-quality OA expansion .
🔍 Summary Table
Initiative Area Key Highlights
Early Leadership First general physics OA journal (NJP, 1998)
Open Physics Programme Holistic OA strategy: access, transparency, inclusivity
Transformative Agreements Hundreds of institutions, global OA publishing access

📘 Final Thoughts
IOP is at the vanguard of physics publishing transformation. By combining legacy leadership (like NJP), strategic policies (Open Physics, data sharing, transparent peer review), and global partnerships (transformative agreements, SCOAP³), it is reshaping scholarly communication in physics.
This approach balances author choice and funder mandates, upgrading both the accessibility and integrity of research — while maintaining high standards of peer review and ethical publication.
If you’d like to explore any of these initiatives in depth—such as the SCOAP³ model, data-sharing policies, or transformative agreements—just let me know.
