If you want to lean more about Ajami in West Africa two other projects could be of interest :
Ajami Lab in Hamburg, is a 12-year research project coordinated by Dmitry Bondarev and supported by the German Research Foundation (Deutsche Forschunsgemeinschaft, DFG), working to 1) catalogue Ajami manuscripts held in private and state collections of Mali and West Africa and to 2) carry out historical and linguistic analysis of the material brought to light by the cataloguing process.
Their blog is a companion to their research focused on historical and modern instances of Ajami—that is, sub-Saharan African languages written in Arabic script—we aim here to share updates, anecdotes, and conceptual and methodological tools as we work to catalogue and analyse African Islamic manuscripts. In doing so, the blog will serve both other scholars of Ajami as well as a wider audience of scholars interested in the insights that can be gleaned from these understudied documents and literacy practices.
The project ʿAjamī Literature and the Expansion of Literacy and Islam: The Case of West Africa coordinated by Falou Ngom at the Boston University African Studies Center will digitize a unique selection of manuscripts in ʿAjamī (African language texts written with a modified Arabic script) in four major West African languages – Hausa, Mandinka, Fula, and Wolof, transliterate and translate them into English and French, prepare commentaries, and create related multimedia resources to be made widely available within and beyond the United States.
