Private and public libraries in the fabled Saharan town in Mali have already collected 150,000 brittle manuscripts, some of them from the 13th century, and local historians believe many more lie buried under the sand.
The texts were stashed under mud homes and in desert caves by proud Malian families whose successive generations feared they would be stolen by Moroccan invaders, European explorers and then French colonialists.
Written in ornate calligraphy, some were used to teach astrology or mathematics, while others tell tales of social and business life in Timbuktu during its "Golden Age," when it was a seat of learning in the 16th century.
Not really archaeology, but history. Interesting though.
