Dude, I don't think you begin to realize the scope of what you are asking. And if your buddy is truly thinking about doing a book about aircraft lost in Yugoslavia, then it would behoove him to do the research himself - to trust what he finds on the net verbatim is pretty foolish. There are lots of sources where you should be able to find much of the information you seek, but if you and your buddy aren't willing to put in the time to find it, why do you think I would? Now, if you're asking for suggestions for where to find source material - books, records, etc. - that's a different story and a reasonable request. Sorry if this sounds harsh, but that's the truth of it.
Here's a good start -
