Sherds, or potsherds, are the pieces of broken pottery found at archaeological sites. They help archaeologists reconstruct past societies by providing insights into ancient cultures' trade, technology, and daily life.

The Lachish Letters are a collection of ostraca (inscribed pottery sherds) discovered in Lachish, Israel, dating back to the 7th century BCE. They provide valuable insights into daily life and administrative affairs in Judah during the final years before the Babylonian conquest in 586 BCE.
