"RAMBI - The Index of Articles on Jewish Studies - is a selective bibliography of articles in the various fields of Jewish studies and in the study of Eretz Israel. Material listed in Rambi is compiled from thousands of periodicals and from collections of articles - in Hebrew, Yiddish, and European languages- mainly from the holdings of the Jewish National and University Library, a world center for research on the Jewish people and Eretz Israel. The main criterion for inclusion in the bibliography is that the article be based on scientific research, or contain important information for such research. [...] Rambi also lists articles from secondary sources."
