Heather, these are useful data, but in the interpretation of these we will have to reckon with journal size distributions. What would be helpful is having data on the number of articles in these journals. It is very likely that smaller journals are overrepresented in the non-APC OA group and that the share of non APC OA output by number of articles is substantially lower than 64%. Maybe 50 percent or even 40? I do not like guessing, so I hope someone will look into this and come up with some data based on article counts.

Although there may be differences between this sub-sample and journals entered in DOAJ before March 2014, this ratio is similar to what we reported earlier and others have been reporting for some time. The text file supplied by DOAJ has been added to the OA APC dataverse: http://dataverse.scholarsportal.info/dvn/dv/oaapc If anyone would like to transform the text file into .csv or other spreadsheet-manipulable file, that would be helpful. For example, this kind of processing would make it possible to provide a much more human readable title list.
