A Torah database (מאגר תורני or מאגר יהדות) is a collection of classic Jewish texts in electronic form, the kinds of texts which, especially in Israel, are often called "The Traditional Jewish Bookshelf" (ארון הספרים היהודי); the texts are in their original languages (Hebrew or Aramaic). These databases contain either keyed-in digital texts or a collection of page-images from printed editions. Given the nature of traditional Jewish Torah study, which involves extensive citation and cross-referencing among hundreds of texts written over the course of thousands of years, many Torah databases also make extensive use of hypertext links.
