I learnt presentation skills primarily via experience. However, later skimmed through a couple of books. Search for Jerry Weissman, I found his book quite good. There would likely be many more (which is why I did not name any in my parent post), so you may want to research yourself a bit also.

Edit: I assumed you are asking about a book on presentation skills, since that is only place where I had mentioned books.

I have also come across a good book on surviving corporate politics, that taught things I had learnt the hard way. I do not remember the name or title, but an Amazon search should help to find a similar book.
