And the other thing about libraries,
@Clix Pix, is that - irrespective of whether I was a child, a nerdy bespectacled adolescent, a student, a university teacher - or now, somewhat later in life - no matter what material I requested from the library, there was simply interest, encouragement, enthusiasm and engagement.
This has not always been the case in bookshops, when - yes, it was infrequent, but it did happen, and not just once or twice - moreover, it was something that occurred only when the shop/store assistant was male, and I was toting heavy (literally and figuratively) quantities of serious tomes about history and politics or socio-economic stuff and would be met with a surprised comment about my selected reading material.
"Heavy reading, huh?" commented the dude manning the till, with a surprised smirk, not long - a couple of years - after the Fall of the Wall, as I hauled some serious stuff on Russia, the USSR, and Central & Eastern Europe to the till. "Not really," I replied, (I hadn't picked up immediately on his condescension and incomprehension, for I was too focussed on balancing my books and extracting my wallet to pay for them, however, my male companion was furious, quivering with mute outrage on my behalf, "they'd never say that to a guy!" he burst out afterwards), "I'm teaching this stuff," (which was true, teaching it at an ancient and venerable university a few hundred metres/yards from that very bookshop), a response which silenced the dude, who stared at me.
