Some time ago, I compiled a bibliography for my exams on comparing Atlantic and Indian Ocean diasporas from Africa. I present here the rough list, in case folks would like to build on this work or utilize it for teaching or an exam question. The problem of comparisons are many, but the rewards when done well are potentially great. One major problem is that there is far more information on Atlantic African diasporas, and the literature is much more voluminous. On top of this, movement and migration in the Indian Ocean predates that in the Atlantic by several millenia. There is also a question of the usefulness of the terms "African" and "diaspora" in an Indian Ocean context. The following is far from a comprehensive list, and is especially weak on the enormous literature on the black Atlantic. I am not sure that "littoral culture" and "African creoles" belong together, but I wanted to give some sense of the parallel processes of identity making and their contexts in each basin.
Lots to chew on here, so happy reading!
