Otzar HaHochma is the world's largest digital library,

containing more than 110,564 Judaic books, scanned page after page in their original format.

The compilation and scanning of the Jewish books began in Jerusalem sixteen years ago by Ohr HaHochma Ltd publishing house. The efforts of a first-rate team of Jewish studies scholars and premier IT-Professionals turned Otzar HaHochma into a world-renowned brand. Otzar HaHochma continuously expands its collection of ebooks and improves the unique software. G-d willing 5 ,000 new titles are added annually.

Otzar HaHochma is the most comprehensive Judaica site of Jewish and Israeli books. The books encompass all realms of Judaism from ancient times to the modern period. The highlight of Otzar HaHochma's software is its sophisticated search engine, based on Optical Character Recognition (OCR) with a very high precision rate, which allows maximum accessibility to the content of the Israeli books simply by typing a word or sequence of words.
