There are, to my thinking, two versions of the cover letter you send with a manuscript.
1) Short 'n Sweet: Dear Editor, this is about blah, de and blah which is significant because zippede. I think this will interest your readers, Sincerely, R. E. Squirrel
2) The Fluff Job. This is the one that goes on for two pages about how awesome the paper is and why it totally is new and solves cold fusion and shit like that.
I have always been a Short and Sweet kind of guy.
It has only recently come to my attention that people go ON with their cover letters.
Do any of y'all with Associate Editor or EIC type experience read those long winded letters or do you just go straight to the Abstract?
