List of Preferred Stock

I've been already calling the NYSE and looking into the S&P website but I cannot find a list, which states which companies have preferred stock out.

Does anybody have a clue where to find such a list of companies since I'd like to invest in pref. stock...

Thanks in advance.

Thanks!

Is there a site providing these lists without registration?

Like in a pdf or similar?
