Came across the MA from Google for stuff on Stonehenge - great site! :)
Read the stuff about the archive scandal. Erk! A bit of Googling to find out more about it showed http://ads.ahds.ac.uk/catalogue/archive/stonehenge_eh_2005/ that the stonehenge archive is in Salisbury museum with the finds, and you can download a of database of it all (but it looks like just tables of data). Doesn't sound ruined to me!
"The archive, including copies of the databases (on paper and CD), is held at Salisbury Museum, which also holds the majority of the finds and some original archive material." :-)
