We've recently gotten a number of scans from the Carnegie Mellon University Archives, and I've posted them in the "Photos from the CMU Archives" gallery. In addition, we are working on getting many more scans from the archives.
Unfortunately there are minimal descriptions for the scans, or in some cases no descriptions. If you can identify anything in the picture ( time period it was taken, people in the picture, buggies in the picture, etc ), feel free to add the info to the comments for that photo. Let the commenting begin!
