Congratulations to Boston University on the launch of their African Ajami Digital Library! This follows another collection of texts hosted at Michigan State’s African Online Digital Library, Harvard’s ASK-DL, and a research collection on Tijāniyyah and the Fayḍah maintained by the Medina Baay Research Association.
The Library of Congress also hosts a fully imaged set of 32 Islamic manuscripts from Mali, which are written mainly in Arabic. While full-text digital search and complete translations are not yet available, there are some indications of use of ajami characters in this set as well. A longstanding project to catalog four collections at the Herskovits Library at Northwestern, begun under John Hunwick, has continued in various stages since 1991.
