Citations and Paper Length

Interesting paper on astro-ph this morning from Kris Stanek. As it turns out, in general, longer papers tend to get cited more. The exception is that, in astronomy, two of the major journals have a "Letters" section, which limits papers to 4 pages. These Letters do tend to be cited more than other short papers (presumably because they are Really just longer papers squeezed into a shorter format). Thus the graph of number of citations versus page length looks an awful lot like the state of Ohio:
The paper also includes some silliness-tinged career advice.
