Produced in the middle of the 4th century, Codex Sinaiticus is one of the two earliest Christian Bibles (The other is Codex Vaticanus in Rome).

Published date:
Parts of the manuscript are now held by four institutions: The British Library, Leipzig University Library, St Catherine’s Monastery at Mount Sinai, and the National Library of Russia. The Codex Sinaiticus Project undertook to reunite the manuscript electronically. It had five principal activities: historical research, conservation, digitisation, transcription, and dissemination. Details of these activities, and the findings of the researchers working on the project, can all be found on the Project website.

Two conferences celebrated the work of the Project. The first, at the British Library, was held on 6-8 July 2009. The proceedings were published in June 2015:

Codex Sinaiticus: New Perspectives on the Ancient Biblical Manuscript, edited by S. McKendrick, D. Parker, A. Myshrall (London: The British Library, 2015).

The second conference was held at the National Library of Russia, St Petersburg, on 12–13 November 2009. The proceedings of this conference were published as E. V. Krushelnitskaia and Z. L. Levshina, eds, Синайский кодекс и памятники древней христианской письменности: традиции и инновации в современных исследованиях, Proceedings of the International Research Conference ‘Синайский кодекс. Рукопись в современном информационном пространстве’ (Fifth Zagrebin Readings), Saint Petersburg, November 12–13, 2009 (Saint Petersburg, 2012).

Other publications resulting from the project included a print facsimile, published by the British Library and Hendrickson’s, and a popular book by Professor David Parker.

The project website continues to be maintained and there are plans to update its content periodically.
