Publishing volume and impact
Over the past five years, more than 305,000 articles have been published open access with Wolters Kluwer, representing over half of our total publishing output. This places us among the leading health sciences publishers worldwide.
Our OA share grew steadily between 2020 and 2023, peaking at 57 percent. In 2024, output declined in line with a market-wide adjustment across the health sciences, where overall OA outputs dropped from 63 percent to 49 percent. Read more about the 2020–2024 trends.
Our OA output spans every area of health sciences (across 68 categories in SCIE). In 2024, General Medicine accounted for 70 percent of our output, followed by Biochemistry and Molecular Biology (7 percent), Health Professions (4 percent), and Dentistry (4 percent). Smaller shares came from Psychology, Neuroscience, Nursing, and other allied fields.
But scale tells only part of the story. Wolters Kluwer open access articles are cited twice as often as paywalled articles3, underscoring the visibility and influence of the research we publish. What distinguishes Wolters Kluwer is how we balance growth with equity, ensuring quality, and extending the reach of research.
These three elements — accessible publishing, trusted quality, and broad global readership — show the full impact of our open access program.
