This digital collection of nineteenth-century manuscripts in Arabic comes from the world reknown archives in Timbuktu. It relates to the slavery and manumission of Africans in Muslim societies. From the Bibliothèque Commémorative Mama Haidara in Timbuktu, Mali.
Note that access is throught the Center for Research Libraries which is a membership organization for libraries worldwide (i.e. this is not an Open Access resource). Since the preservation of Timbuktu manuscripts has been in the news, the resource is topical for the global academic community.
In related developments, I’ve run across several books relating to the recent conflicts around and across the Sahara:
