Just a question...

I haven't gotten to the really exciting reading yet (I presume), but I do have a question from WSG -- if anyone can help. The authors recommend "downstyle typing," which is a term that is new to me. This is where in Web sites, the headlines, subheads, etc. have only the first word capitalized, unless there is a common noun. It seems to me that many times, these headlines are used as the site title or page title. And many times, I have seen "article" titles with only the first word capitalized now. Look at headline on USA Today's site. So, on a Works Cited or bib page, how does one present these? Do we write up the title as it appears on the web page, with only the first word capitalized? Or do we fix it as a reference should appear? Just wondering if anyone has a clue.
