Did you know that you can access millions of high-quality articles from peer-reviewed academic and clinical journals for free? Many funding bodies now insist that articles based on research that they have paid for must be made available for free for anyone to read. These articles are stored in thousands of different subject and organizational databases across the Web, but there are a number of 'one-stop' search tools that will help you find articles on the topics that you are interested in. Take a look at our Open Access Articles tab in this guide to try some of these out. 


The Oxford University Research Archive (ORA) is a digital repository of research publications produced by members of the University. For more information about ORA, including depositing and finding articles, see our help guide. To find out more about Open Access at Oxford please visit our dedicated website.
