@Steeeve In Egypt, something like this happened. Look up the "Oxyrhynchos papyri". Short version: Oxyrhynchos was a bustling city in antiquity, the canals supplying the water fell into disrepair after the muslim conquest, and the combination of dry desert climate and low population kept a lot of the papyri (which were just dumped in the desert) in good state. British archaeologists re-discovered the papyrus dumps over 100 years ago, and they proved to be a goldmine of ancient texts (from administrative paperwork to poems and philosophy), still being analyzed and yielding new results until today.
