The referring URL was http://en.m.wikipedia.org/wiki/Our_Boarding_House which means they came to our finding aid via the link we placed on the "Our Boarding House" Wikipedia article and they accessed the article on the mobile version of Wikipedia.
I hadn't heard of EPUB, will have to check into that. Thanks!

Michele - that's really interesting. Do you know how they got to the
finding aid (e.g. from a Google Search)? I've been struggling with
this idea a bit. In my opinion, most web-based finding aids don't lend
themselves well to use on mobile devices. I've been intending to look
into transforming an EAD finding aid into something like EPUB  to
allow it to be viewed with eBook reader software and hardware, but I
haven't had the time yet.
