The Center for the Study of New Testament Manuscripts has uploaded new images of Codex Sinaiticus. The images are from the full-sized black and white facsimile of the manuscript edited by Helen and Kirsopp Lake and published by Clarendon Press (NT 1911, OT 1922). The images posted are of the New Testament, the Epistle of Barnabas, and the Shepherd of Hermas.
For those who are interested in the Old Testament portion of Sinaiticus, Tischendorfâ€™s 1862 facimile edition of Sinaiticus is availble online from the Biblical Manuscripts Project.
For an introduction to this manuscript, see my Codex Sinaiticus: A Profile (TCHB 5)
