In reply to Sinisha Juricic's post on Fri 10 Jul 2009 :
Assume you're talking about international distribution.
A lot depends on what you mean by literature, and on the exact topic your paper covers.
If it's sales brochures etc, many of these will be online; just google and see what you come up with.
Also find out which person within BBC Worldwide, National Geographic Television International and other large distributors deal with Croatia and ask them for advice on where to find literature.
If you mean books or papers on the distribution business, I haven't ever come across any, though that doesn't mean they don't exist.
