Hi there..
I'm having my first encounter with trying to publish something, and am a bit confused regarding the role of the cover letter for the submission of articles. The journal I'm targeting wants four copies of the article in paper for first submission, and doesn't state anything about cover letter policies. I have read conflicting information about this on the net -- some say you should advertise your paper and state why the journal should publish it, others say a few lines of "enclosed you find blabla for your consideration" would suffice. My supervisor seemed to think the latter variant ok, but I'm still a bit confused. How do you normally do it? I'm in the social sciences, in case that's relevant.
