Interesting study on PLoS One - highlighting the fact that in the same way the top 1% of the population have a huge share of capital compared to the lowest 10%, a similar inequality exists in science publishing.
plosone.org/article/info%3A...
One percent of scientists are responsible for a whopping 41% of all papers published - and there is a very noticeable elite when it comes to multiple publications per year:
Two or more: 68,221
Three or more: 37,953
Four or more: 23,342
Five or more: 15,464
10 or more: 3269
Should we be concerned about this publishing inequality? Are the other 99% of scientists being unfairly ignored or lack resources and time to publish
