Open-access publishers

Funding
Since open access publication does not charge readers, there are many financial models used to cover costs by other means. Open access can be provided by commercial publishers, who may publish open access as well as subscription-based journals, or dedicated open-access publishers such as Public Library of Science (PLOS) and BioMed Central. Another source of funding for open access can be institutional subscribers. One example is the Subscribe to Open publishing model introduced by Annual Reviews; if the subscription revenue goal is met, the given journal's volume is published open access. The number of journals implementing this model grew from 192 in 2024 to 378 in 2025.
