One of the largest and most valuable ketuba (Jewish marriage contract) collections in the world now appears on the Internet site of the Hebrew University library, at http://jnul.huji.ac.il. The collection includes more than 1,200 original ketubot from 60 different countries, covering a time period of over 900 years; the collection is considered to be a major resource for research in Jewish history, law and art. Each ketubah in the collection is depicted on the site in three different sizes in order to permit detailed examination. Details of each ketubah are also presented, including the names of the married couple. Searches for particular ketubot can be made according to various parameters, including country, city, date and names. The display of this valuable collection worldwide is part of the library's digitalization project, made possible by a contribution from the David and Fela Shapell Family of Los Angeles. Further digitalization is planned of various collections in the library, including manuscripts of various types, historical records of Jewish communities, ancient maps, and recordings of Jewish liturgical and folk music.
