martin cohen's “developments in foreign approval buying,” in the march 2001 issue of pmla, lists some of “the foreign language bibliographer's […] tricks” (393) for stocking collections. Acquiring African literature, however, is largely a different matter. The approval plans Cohen mentions, whereby “the vendor allows you to see the book [or a description of it] before you decide whether or not to add it to the collection,” would be applicable to the presses in England and France specializing in Third World literature (e.g., Heinemann in England, L'Harmattan in France), which publish primarily the most established African writers (see Maja-Pearce; Ruppert). But when it comes to publishing on the continent of Africa, even books by well-known writers (like Ngũgĩ wa Thiong'o), when written in the national languages, can only be obtained locally. And certainly all other literature has to be bought in the country of origin.
