A concrete expression of the nationalist positivism expressed in the manifesto in Zion, and a scholarly analogue to the Zionist goal of ingathering Jews from around the world, was the initiative undertaken by Dinur to establish the Central Archives of the Jewish People and Yad Vashem and with the support of David Ben-Gurion himself in 1950, to gather together eventually in an Institute of Microfilmed Hebrew Manuscripts, copies of over seventy thousand Hebrew manuscripts located in libraries around the world. The microfilms of Hebrew manuscripts and the archival documents were considered part of a Jewish モnationalヤ heritage. As a result of the young Israeli governments support, Israeli medieval Jewish scholarly research based on these thousands of Hebrew manuscripts, as well as archival sources, became one of the defining features of certain kinds of Israeli medieval Jewish historiography.

Although Hebrew manuscripts obviously were used earlier in Europe and the U.S. before the Institute came into existence, it encouraged their systematic use as never before by making them all available in one room, and only in Jerusalem.
