The history of exchange forces

 I almost missed this paper submitted to to the history and philosophy section of arXiv last week, but picked it up when reviewing recent cross-post submissions to the nuclear theory section.  It is called "The development of the concept of exchange forces in the 1930s: close encounters between Europe and Japan and the birth of nuclear theory"

Aside from my general interest in history and the history of physics in particular, the last two words of the title definitely put it on-topic for my interests.  Hopefully I will get round to reading it, but thought it might be of enough interest to post here even before (if) I do read it.
