The official documents series is broad, focusing mainly on items from the categories of state (passports, travel papers, marriage certificates, report cards) and business documentation (contracts, lawsuits, personnel lists). The most prominent parts of the collection are the identification papers and other state records for Walter, Hertha, and Adolf Klinger, encompassing the personal side, and the details of business deals that Walter was involved in for Warner Bros. and his own companies, on the business side.
