@OmSigDAVID,
Well, first, Powell's - did you get there?
then the place in Long Beach, CA - something about a Thousand.
Marlow's in Santa Monica, what low lifes, I loved it. To get to the bathroom you had to pass porn.. Some of my favorite books are from there, early italian stuff, plus old crime thriller paperbacks.
An antiquarian place in San Francisco, way above my purview
The Michelangelo library in Firenze
Where an olden abuzzer posted, Touissant? in Paris. She was so smart on books...
The early Hennessey & Ingalls re architecture et al.
Rizzoli, in New York, I just walked past it, just as well. I could not have not bought something.
The library that was closed in the Palazzo Pilato in in Parma - re Bondoni.
