I have had unexpected pleasure from finding the attached list of New York architectural bookstores. It gives an opportunity for vicarious browsing, as well as listing stores I don’t already know.
I thought I still had a bookmark from McNally Jackson, his favourite New York store as well as mine, but they only allow one bookmark per purchase which means they are always in short supply, as opposed to the bookmark of University Press Books in Berkeley, California, my second favourite, of which I still have a plentiful supply in spite of not having visited the store since 1991. Also, the Corner Bookstore on Madison at 93rd. which was a benefit of staying in the Hotel Wales.
