Question: What was all found in the dead sea scrolls?

Disambiguated questions and answers:
context: The Dead Sea Scrolls (also Qumran Caves Scrolls) are ancient Jewish religious manuscripts found in the Qumran Caves in the Judaean Desert, near Ein Feshkha on the northern shore of the Dead Sea. Scholarly consensus dates these scrolls from the last three centuries BCE and the first century CE. The texts have great historical, religious, and linguistic significance because they include the second-oldest known surviving manuscripts of works later included in the Hebrew Bible canon, along with deuterocanonical and extra-biblical manuscripts which preserve evidence of the diversity of religious thought in late Second Temple Judaism. Almost all of the Dead Sea Scrolls are currently in the collection of the Government of the State of Israel, with ownership disputed with Jordan and the Palestinian Authority, and they are housed in the Shrine of the Book on the grounds of the Israel Museum.
