I had some free time 
in the city, while waiting the bus, so I'd tried almost on all the libraries in there (but one) to buy the books I've gave away to my aunt: they were the three sci-fi books published locally last years: no one was even knowing about them.
I'd hear about the books on local radio, in various episodes there were interviews within the authors, too; while it's something new as a genre in here, for the local publishing's topics, I felt quite disappointed that the librarian wasn't to even know about, about none of three.
One book was entirely in friulian, and the author keeps also a contest that endures the whole year, online, to enhance short stories' writers, within a competitive challenge that doesn't last just a period, but continues endless; so he's someone not stranger, really.
One book was presented within a site, and on socials, showing a fake village as it was real (the village narrated on the book): it was fun and someone like me that doesn't knew the area might even have been tricked to think there was a real place in there (

But yeah, the librarians were only to know what their salespersons menage.
