Bryan Alexander linked to this William Pannapacker post on digital humanities at the Chronicle. One of the projects it describes is mapping the movements of characters in a Virginia Woolf novel.  This reminded me of a book I just read, The Far-Traveller: Voyages of a Viking Woman by Nancy Marie Brown.  Archaeologists do things very much like the Woolf project in trying to look for clues as to what might have been accurate in an Icelandic saga.

I have for the moment forgotten the other thing I meant not to forget, so I will edit later.
