Little Free Libraries predominantly appear in medium- to high-income neighborhoods in Toronto (an effect that is less pronounced in Calgary, a wealthier city). For both cities, Little Free Libraries are distributed almost exclusively in neighborhoods where 25 percent or more residents have university degrees. In Toronto, Little Free Libraries sprout where public library branches are plentiful and where neighborhoods are white.That's based on an article in something called the Journal of Radical Librarianship. "Little Free Libraries®: Interrogating the impact of the branded book exchange." Again with the "interrogating," as if these people are indulging in fantasies of working enemies of the people over in Lefortovo rather than signalling their prejudices. "We are not trying to empirically demonstrate that LFL® has caused damage to traditional public libraries, rather we seek to provide an alternative and critical point of view as a departure from the LFL® narrative that has taken hold in the mainstream media." Whatever.
Translating from the academic-speak: We don't have any evidence, but we want to demonstrate our Politically Correct bona fides and fatten our tenure dossiers.
