The manuscripts had survived for centuries in Timbuktu, on the remote south-west fringe of the Sahara desert. They were hidden in wooden trunks, buried in boxes under the sand and in caves. When French colonial rule ended in 1960, Timbuktu residents held preserved manuscripts in 60-80 private libraries.The vast majority of the texts were written in Arabic. A few were in African languages, such as Songhai, Tamashek and Bambara. There was even one in Hebrew. They covered a diverse range of topics including astronomy, poetry, music, medicine and women's rights. The oldest dated from 1204.
