Article-level metrics

Like Comment

You might have noticed one or two excited tweets from us earlier today about this, but if not, here it is again: article-level metrics are now available on 20 journals on, including us! — the press release is here.

An example of one of our metrics pages can be found here. At the top of the page, there are citation counts from Web of Science, CrossRef and Scopus. Under that are more social metrics, from sources such as Twitter, Facebook, Reddit, Google+, blog posts and news outlets. The box to the right then provides links out to the news and blog coverage. Here’s a screenshot:


Further down the page, you get to see the number of page views and how they change over time. You can mouse-over the data and see the number of views on any given date. There are definitions on each metrics page about what is counted in each section, but basically page views amount to the total of full-text html views and pdf downloads. Here’s the data for the same paper featured in the screenshot above.


You’ll notice an increase in the rate of views just below 2,000 views — interestingly, this corresponds to the paper being published in a monthly issue on that date. The views before that are from the paper being published online in advance of print. For some of our papers, you wouldn’t even notice any transition; the views smoothly increase and the issue date doesn’t have any impact. On the other hand, for some papers (such as this one), going into an issue makes a big difference. I haven’t really thought about why different papers are affected in different ways — so at the moment I have no idea why.

And although we can’t link directly to tweets about a paper (complain to Twitter, not to us), you can see the geographical breakdown of them. The paper associated with the screenshots above doesn’t have a lot (see below), but here’s an example of one that does — scroll down to see the map!


Anyway, there you go. We’d be interested to hear what you think about these article-level metrics — comment away!
