One of the first picture books for children was "Orbis Sensualium Pictus" ("Visible World in Pictures"), published by Johann Amos Comenius in 1658. Born in the present-day Czech republic, Comenius was a theologian and education reformer who believed in teaching children from a Christian perspective. His book, with 150 woodcut images, was popular across Europe for centuries. The Library has a 1664 edition published in London.
The Library recently put online some 230 histortic manuscripts, some of them more than a thousand years old, in Hebrew and similar languages, such as Judeo-Arabic, Judeo-Persian and Yiddish. The collection, available online for researchers and the public for the first time, includes a 14th-century collection of responsa, or rabbinic decisions and commentary, by Solomon ibn Adret of Barcelona, considered one of the most prominent authorities on Jewish law.
