Speaking of more recent history, every time I hear about a Carnegie library I am amazed at how putting public libraries in cities large and small (Orosi, Exeter, and Dinuba, but not Reedley?) changed the United States. Fresno's was impressive
Funded by a 1901 Carnegie grant of $30,000, and completed in 1904, the Fresno Carnegie Library was one of the earliest and costliest of the Carnegies.but was a victim of the tear-down fever of the late 1950s to mid 1960s. Another casualty was the Fresno Country courthouse from 1875, you can see the dome crashing down here (page 73).
One more thing: these photos from the VAB at KSC reminded me of the few (two?) times I was in the building with a shuttle in some state of integration with the external tank and SRBs. I remember going in a side door where we were given a brief safety briefing (like the one you get on a tour of Vandenberg before go into a room with a missle) and we had to put our ID badges in slots on the wall before we went into the main part of the VAB. Our guide said it was so that if something went wrong they would know who was in the building :)
