This dataset, extracted from Robert Singerman’s 1990 publication of Judaica Americana, contains bibliographic data of publications before the year 1900 pertaining to Jewish people, Judaism, and Jewish culture published in the United States, in any language. The data is primarily stored on the research data repository site ScholarlyCommons at the University of Pennsylvania, and it powers an Omeka site of the same name. Reuse potential of the data includes its use as a reference tool for early American Jewish history and history of the book, historical bibliometric data, book trade documentation, and as a support for the extant study of digitization efforts in research libraries.
