There are some good photos here of the rescue action, including the big hall
where the rubble is being sorted; they're now talking about taking up to a
year on site, are putting a roof over the area, & apparently tearing down a
third house that's in danger of collapsing; also some of the links have film
clips where parallels are made to the Anna Amelia library fire a few years
back. Also, until the second missing student (assumed dead at this point) is
found, archive work on site is still second to the attempt at rescue work...
