We’ve been busy gathering data from publisher websites and other sources since mid-May this year. Our recent check of the top publishers in DOAJ by number of journals illustrates that there is so much change in this area that it’s going to take a while longer to complete this data. In future we’re not even going to attempt a short-term annual census period, rather pursue the gathering of data on an ongoing basis which will permit richer publisher case studies along the way. In the meantime, if anyone can make use of the 2,286 journals that we gathered APC data for or the 103 journals that we gathered article page processing charges for, this plus all the other data we have gathered from various sources, as well as detailed documentation is now available in the OA APC dataverse: http://dataverse.scholarsportal.info/dvn/dv/oaapc/faces/study/StudyPage.xhtml?globalId=hdl:10864/11269&studyListingIndex=2_dc438dc55e8a1e8d291f4fad61a9

We hope this is useful. Informal peer review (please check the documentation for the many limitations to this dataset already noted) in the form of comments to this post are most welcome. We will continue with data gathering and analysis so watch for further posts.
