Actually, that's a standard XML interface with a stylesheet rendering the html.  The "static" message is probably coming out of my database configuration.

Subject: Re: [CODE4LIB] WorldCat Terminologies

Yeah, the statement that it's a static copy from 2006 would have stopped me in my tracks if I had somehow happened accross the page, which I probably wouldn't have, but now I've bookmarked it so I might find it again -- but will probably forget that it's REALLY up to date even though it says 2006 on it. Nice catch Karen. 

Karen, that looks to me like an HTML front-end for an SRU service, I bet it's got an SRU api. Which one of these days I'll get around to figuring out how to write code for.

Unfortunately, that page states right up front:

"A static copy of LC's Name Authority File from February of 2006"

That might confuse visitors. Maybe a quick revision is in order? :-)

Also, API access?
