Using the IndieBound Goggle mash-up app, no indie bookstores are located in the Bronx. As seen here:
That one bookstore in the bottom left corner is in Manhattan. So I checked agaisnt Google Business locator in Maps, and I found only 3 major bookstores, some college bookstores and a few Christian retailers.
Contrast that against the total population of the bourough with the fact that "50.7% of the total population were Hispanic or Latino of any race (23.3% of Bronx's population were Puerto Ricans) and at least 524,410 residents were born abroad/overseas, according to Wikipedia.org.
If the Bronx is really on the up and up, I think we need more bookstores in that area.
