I'm curious about the request for slides of museum architecture, and notice that there hasn't been much response on the list. What exactly are you asking? Do you want to buy slides or are you hoping that people will give or lend you views of their own institutions? I probably have a few of my own museum and several art museums that might interest you, but I don't usually lend them. When I prepare slide lectures, I usually take my own photographs and/or buy commercial slides. I'm not sure what you have in mind. --David Haberstich
