Access for low-and middle-income countries
In keeping with our role as the UK's national academy of science, we offer free access to readers in low-and middle-income countries.
The Royal Society’s Philosophical Transactions, launched in 1665, was the world’s first scientific journal. It established the fundamental principles of scientific priority and peer review.
Most of our oldest content is now freely available, specifically, all papers older than 70 years. In addition, papers published between 10 years ago and either 12 months ago (biological sciences and history of science) or 24 months ago (physical sciences) from online issue publication are freely available. For Biographical Memoirs all issues are now freely available.
Please refer to the table below for an overview of the freely available content in our journals.
