When I started at UCLA in 1974 there were several bookstores like that in Westwood, "the village" we called it, in unconscious longing for Manhattan. I learned as much about literature and art walking the aisles of these stores with their floor to ceiling stacks of used books on every subject as I did in classes. Before the internet it was actually hard to find out about things outside the mainstream. The used bookstores of Westwood provided a resting place for the engaged mind.
These stores weren't put out of business by Amazon, they were put out of business by the big chain bookstores and the university claiming local business for itself. This is why I had a hard time feeling much sympathy for the chains when they fell to progress. They were a step on that road and did not last long at all in retrospect.
I remember walking the same aisles as the stores closed and were replaced by video game parlors and greasy grease burger joints. The last remnants of the fabulous human culture on display had a sad sameness about them. All that was left were failed self help books, out of date tax advice tomes and endless boxes of ancient NatGeos no one needed because they already had boxes of their own at home in the garage.
I did not sense then the passing of a moment, but there it was.
