What’s open access, what’s closed, and what’s in between? Figuring it all out can be complicated and confusing. This clever Venn diagram by Ian Farquharson highlights the different levels of open access in scholarly publishing, as a function of cost to the readers and authors, copyright retention, and peer review. It’s a helpful tool to better understand and explain how scholarly publishing works, and what options are available to you (and your audience). It’s worth noting too that some journals have a hybrid open access model, which means some articles will be freely available while others require payment or subscriptions.
