Really short articles in good journals? I wonder in some good journals, there are articles that are quite short. Maximum 10 pages. How come such papers, with quite a short introduction with a brief lit-rewiew, are published? They are because of the quality, to do point conclusion and precise findings?
In physics, a lot of “letter” journals or sections of journals limit the contribution to a few pages.  The better known example is Physical Review Letters where the current limit is 3750 words, or about 5 pages depending on figures etc.  (The one recent exception is the initial paper on gravitational wave detection, which was allow to go well beyond the normal page limit).  PRL is currently ranked top physics journal
by Google and its Clavirate impact factor score is also one of the highest for a physics journal.  People read it precisely because it’s to the point and usually timely.
