Generally what you're looking for is "research reports" of the team. These are the original versions of the published papers, before details have been cut out to fit a page limit. If you're into brevity, you can also search for PhD theses of one of the co-authors within a similar time period as the interesting article. I believe in vast majority of papers the footwork is done by a PhD student, that will then incorporate the thing into a thesis. If all else fails, email the authors.
