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. A Torah database usually refers to a collection of primary texts, rather than translations or secondary research and reference materials. Digital Text Software Packages The Bar-Ilan Responsa Project The very first such database was the Bar Ilan Responsa Project, which began in 1963 at the Weizmann Institute in Israel, migrated to Bar-Ilan University soon thereafter, and was up and running by 1967. It became available in time-sharing mode from university terminals in 1979, was transferred to CD-ROM in 1990, and version 1.0 was offered for sale to the public in 1992. The current version is number 28 or 28+ (the "plus" version contains an important secondary reference called the Encyclopedia Talmudit). The Responsa Project tries to base its electronic texts on the most accurate printed editions (though it seems that it is sometimes prevented from doing so because of copyright considerations), and it has a reputation for relatively error-free electronic texts based upon those editions. It also features approximately 360,000 hypertext links between the various collections within the database, as well as a topical halakhic index for the Shulchan Aruch and selected responsa. Since its early years it has employed a sophisticated search-engine specifically designed for Hebrew language texts. In recent years (at least since version 10 in 2002), the Responsa Project has made updates available once a year, usually between the Passover and Shavuot holidays, although this varies considerably. Sometimes they release an update after the holiday of Chanukah or after the holiday of Purim. It depends on how much they have completed. In January, 2007, the responsa project became available in an online edition. In April, 2007 the Responsa Project won the Israel Prize for Jewish studies. Currently (as of 2018, version 26+) according to their list the number of seforim listed is about 914 (excluding the Chazon Ish which is
