* Brilliant, kind of moving: last year John Ronan Architects proposed turning the old Chicago central post office into an above-ground burial vault. Lynn Becker has a fascinating look at Ronan's elegiac idea.
* Chicago Tribune, 2006: "Looked at in one way, the $2 million in annual holding costs for just the old Chicago post office could've kept 100 million letters at the old 37 cents rate for first-class postage instead of the new 39-cents rate."
* A fantastic 1931 diagram of the old post office.
* Architecture criticism used to be wicked boring.
