[Updated. I replaced the spreadsheet on figshare twice as a couple of publisher names had to be corrected. This left a version with 101 unique publisher names –note that some might still be subsumable to other publisher names in the set. I have also corrected the first bar chart and added another one two on this post. Please bear in mind there might still be errors in the source data.
