The family of the late Yeshayahu Leibowitz, one of Israel's greatest scholars and intellectuals, had donated his personal archive to the National Library in Jerusalem. It includes journals, articles, books and letters from the correspondence Leibowitz conducted with colleagues and the public.

His family did not ask for compensation but set one condition - that the archive be accessible to researchers and the library cooperate with organizations focusing on preserving and disseminating the writings and legacy of Leibowitz.

The library will put on the Internet millions of items, including archives that to date have been accessible only to scholars. This will take years. The heads of the National Library stressed that the donation was one of the most important in some time. The chairman of its board, David Bloomberg, said: "The library applauds the willingness of the family of Professor Leibowitz to transfer the estate without imposing any essential limitation, an approach inspired by Professor Leibowitz, and we hope that it will serve as a model for emulation by other intellectuals and public figures."

Leibowitz, who died in 1994, was an observant Jew who taught science at Hebrew University for six decades and was an outspoken thinker. He was a prolific writer and was nominated for the Israel Prize in 1993 but announced he would refuse to accept it as he knew his nomination would create controversy.
