With the usual flurry of Impact Factor announcements due to start any day now, it’s a good time to remember that it is the papers, not the journals they´re published in, that make the impact.It also shows the graph below of the citation distribution for the journal. Note how incredibly broad and asymmetrical the distribution is. I found this interesting because several years ago I wondered what the error bar was on Impact factors, which are often reported to several decimal places.
The editorial points out that the distribution is probably broader for PLOS ONE because it publishes articles from a diversity of fields. Hence, I would still like to see distributions from other journals.
