This article is food for thought indeed. I've been convinced for a long time that if a book-buying culture, especially of fiction, were to become common in Africa the potential market would be so huge that it would create an industry big enough to make UK & USA publishers sit up and take notice. Sadly legacies of the past make this a real challenge. Poverty is still widespread as is illiteracy, making book buying impossible and pointless respectively.
Another, less obvious, legacy is mistrust. The first commecially printed books brought into Africa were of European, often British, origin. In many cases they were distributed by missionaries or colonial officials and reflected a particular world view that was condescending at best and hostile to African culture at worst. Till today commercial publishing and the products it distributes are often seen as a "White" thing.
We really need a major publisher of fiction on the African continent giving a voice to local writers, not focusing on reprints of foreign books. I'm not denying that there are African writers finding their way into print or that there are companies doing their best to promote local writers but resources are scarce and print runs small.
Cost is a major problem and it's time for some innovative thinking to get prices down and build a readership from the bottom up, not try to push high-priced Eurocentric publications from the top down. The affluent are a scarce species in Africa and likely to remain so for some time to come.
Just think of the potential waiting to be properly harnessed in Africa, from a publishing and sales perspective as well as in getting the voice of local writers to the ear of local readers.
