Steve Heard just posted a blog on his journal life list – all of the journals in which he has published and how his papers are distributed across those journals. Kind of like a birder’s life list of species. Dividing the number of journals by the number of papers gives a very rough JOURNAL DIVERSITY INDEX (JDI**) for an author – Steve’s is 0.61, which he expects to be high. Although I hadn’t planned to write a blog on this topic, it reminded me that I am always excited when I expand my journal life list, favoring JDI increase. Yet at the same time, I tend to target particular journals that I think are in my core research area, favoring JDI decrease. So I quickly (on the train home) did an analysis similar to Steve’s, with some additions.
* I have included (for ease of generating this quickly), all publications in a journal even if they are introductions or notes or comments or news pieces. For example, my publications in Nature are News & Views and the like.
** This is just a quick and simple metric - see Steve's blog for more comments on it.
