​​The National Library functions as the "national memory" of the State of Israel and Eretz Israel. The Israel Collection is based on The Books Law – Legal Deposit (2000), which requires that two copies of any item printed and published in Israel (50 copies and above) be submitted to the National Library. The materials of the Israel Collection relate to the languages, culture, and homeland of the Jewish people, in Hebrew and in other languages. The aspiration of this top priority collection is to achieve comprehensive coverage of all relevant works, in all languages.
