British Online Archives is one of the United Kingdom’s leading academic publishers. Their goal is to provide students and researchers in the humanities and social sciences with access to unique collections of primary source documents. To this end, the website hosts over 4 million records drawn from both private and public archives. These records are organised thematically, covering 1,000 years of world history, from politics and warfare to slavery and medicine. We currently have a trial to all content on British Online Archives owing to their COVID response offer. It is reviewed each month and extended if deemed necessary.
