The story

Ex Libris started as an internal project at the Hebrew University of Jerusalem in 1980 to develop a new library management system, as no system at the time was able to handle both Hebrew and Latin character sets as required by the university. The software was called Automated Library Expandable Program or ALEPH-100 ("Aleph" is also the name of the first letter of many Semitic alphabets). In 1983, Yissum (the technology transfer company of the Hebrew University) founded Aleph-Yissum Ltd., a new company to commercialize the software. Yohanan Spruch, the original developer of ALEPH, became the company's chief technology officer. Between 1983 and 1988, all eight Israeli universities bought the program and linked up in a network.

In 1986 Ex Libris Ltd. was founded by technology entrepreneur Azriel Morag to market the software overseas. In 1993, ALEPH was deployed by the seventeen libraries of the Vatican

and 200 libraries in 27 countries had bought it by 1995.

In 1995 Aleph-Yissum merged with Ex Libris Ltd. and reorganized as the Ex Libris Group, headed by Azriel Morag as the group's chief executive officer.

In July 1997, Ex Libris acquired Dabis, a leading vendor of automated library systems in the German speaking countries.

In 1998, venture capital funds Walden Israel and Tamar Ventures invested over $4m in Ex Libris.

In February 2000, Ex Libris acquired the rights to SFX, an OpenURL link server software, from the University of Ghent. Ex Libris popularized OpenURL, which later became the ANSI/NISO Z39.88 standard in the information industry.

In July 2000, Ex Libris launched MetaLib, a federated search system that conducts simultaneous searches in multiple information resources such as library catalogs, journal articles, newspapers.

It was the company's first step into the research services market. The company provides services to thousands of customers in more than 90 countries. As of 2015, Ex Libris served 43 of the 50 top universities in the world. Over 40 national libraries use Ex Libris solutions.
