Routes to open access
There are two main routes to making your work available as open access.
You can make your work open access in an institutional or subject repository, without the need to pay open access charges. This is referred to as self-archiving or "green" open access.
Most publishers allow you to archive your accepted manuscript in a repository, although they may not allow it to be immediately open access. The University of Exeter's preferred route to open access is self-archiving in the institutional repository, Open Research Exeter (ORE). Upload upon acceptance, via Symplectic to ORE.
Paying for open access
Many journals offer the option to publish the final version of your article as open access on the publisher website, immediately upon online publication. A licence is applied that describes how others can reuse your work, such as one of the Creative Commons licences, of which the most liberal is CC BY.
This usually involves payment to the publisher of a one-off open access Article Processing Charge (APC) and is sometimes referred to as “gold” open access.
