The monastery library preserves the second largest collection of early codices and manuscripts in the world, outnumbered only by the Vatican Library. It contains Greek, Arabic, Armenian, Hebrew, Georgian, and Syriac texts. The Codex Sinaiticus, now in the British Library, left the monastery in the 19th century for Russia, in circumstances that are now disputed.
