So far we could admire the wonderful Gutenberg bible in Göttingen (1454)
Current students of theology seem to have much better tools… The exciting news are that Codex Sinaiticus (dating back to 350?) is currently being digitized where NT and half of AT will be available in 2 years or so.
In 1844 Konstantin von Tischendorf discovered the Codex in a paper basket at Saint Catherine monastery of Mount Sinai (I also visited the monastery some years ago but did not find anything useful in the basket). He was allowed to take 43 of the 129 sheets to Leipzig. On another visit he discovered even more papers that were donated to Tsar Alexander. In 1933 former USSR sold 347 sheets to the Britische Museum in London, 6 sheets are still in St. Petersburg. In 1975 another 38 pages were found that are still Saint Catherine. At the moment British Library London, Universitätsbibliothek Leipzig, Russian National Library St. Petersburg and Saint Catherine work together for a digital edition of the manuscript including the use of hyperspectral imaging to uncover erased or faded text. This is quite important as Codex Sinaiticus (together with Codex Vaticanus) has heavily influenced our textus receptus.
