Prior to September 1, 2009, a previously unseen fragment of Codex Sinaiticus was discovered in the monastery's library,[33][34] as well as among the New Finds of 1975.[35][5] On other visits (1855, 1857) Constantin von Tischendorf also amassed there more valuable manuscripts (Greek, Christian Palestinian Aramaic, Georgian, Syriac) and took them with him to St Petersburg and Leipzig, where they are stored today.[36][37][38][39][40][41][42]
