A book desert. Like a food desert, a book desert is a place where:
affordable and nutritious [literature] is difficult to obtain, particularly for those without access to a [insert item of choice here: bookstore, cash flow, reading device, ...] (h/t wikipedia)
Don't let the digital age fool you—today's bookmarket climate allows the easy distribution and affordable pricing of current and selling titles. But what about backlist books, nonmainstream books, those needed in translation, those needed in electronically-readable and accessible editions? Those books are often harder to find and prohibitively expensive for those who stand to benefit from them most. Our climate creates the desert.
But the discrepancy runs deeper. Assess a cross-section of backlist books (choose a category) and you will find that the overwhelming majority of books subject to this desert(ing) climate are those by marginalized groups, women, and/or people of color, whereas their counterparts are more frequently passing into programs like print on demand and digital editioning that allow them to be sold and discounted in a manner that stays affordable, and therefore, effective.
Why aren't more books by WOC available digitally? They're at the bottom of someone's list to convert. "Too little time, not enough money", we are familiar with that refrain.
The list is descending based on perceived economy.
The list is descending based on platform.
