Oxford Open wants to distribute journals of high-quality research but to be able to publish the journal in the open access model. They do charge article processing fees for most of their journals. Oxford Open also has journals that the author can choose the open access option (hybrid journals), but for the purpose of our research, we only use the journal that is available fully in open access.
By collecting the information about the open-access journals I noticed that only 14 of their journals don’t have any processing charge and some of them don’t have them, but only for 2016.
On their website I was able to collect 35 journal titles, the DOAJ only has 16. They seem to aim for more journals that will be available without fees for the user.
In 2015 they had 11 journals and we sampled 5 of them. Only two have increased their price and the other three journals the price remained the same. The Journal DNA Research has increased the most of their processing fees in 2016. It has risen by 50%. However, the Nucleic Acids Research has a rise they processing fees from 1400 GBP in 2015 to 1420 GBP in 2016.
