This undated photo provided by the Israel National Library, shows a document from Halberstadt, Germany, written in the 18th century. The library has begun digitizing communal ledgers of modern European Jewish communities, known as pinkasim. The documents, were used by European Jewish communities hundreds of years ago to keep track of financial transactions, political happenings, relations with non-Jewish government bodies, and even funny moments in the communities.
