While looking for a link about the New York Coliseum for my memories of my first job, I discovered that Coliseum Books in New York closed in January. I used to enjoy browsing there, because it was large and varied, but not stuffy or intellectual.
My teenage years in New York involved a lot of browsing in bookstores. I learned many things reading in their aisles. Another favorite was the McGraw-Hill bookstore, in the basement of the McGraw-Hill building. They had technical books on unheard-of topics, and a calculator counter with the latest marvels from Hewlett-Packard. Many a happy hour was spent there.
