Prof. Dr. Muḥammad b. Tāwīt al-Ṭanjī (1918-1974) was a Moroccan scholar of literature, fiqh, and history known for his scholarly publications. The collection includes works on history, literature, philosophy, hadith, astronomy, and many other subjects. The collection, which consists of notebooks, miscellaneous documents, and bibliographic fiches, is organized in three groups. Notebooks constitute a significant portion of the 550 documents. These notebooks, which largely contain academic notes, include bibliographical information, indexes, and various works, as well as research that al-Ṭanjī started but did not complete. The miscellaneous papers include 189 letters. The collection, which dates from 1814 to 1997, is classified in 96 folders and 768 files.
