What happened to the Hammerbooks website?

I just tried to access one of my absolute favourite Hammer sites, the Hammer Books Library, dedicated to an overview over all the various Hammer Books and Magazines out there, but kept getting an error message. Does anyone know what's up with the site? I also don't seem to be able to get any Google reference about it, other than non functioning links from other sites. Please don't tell me that this site is no longer around as that would be a crying shame.
