The New Testament version is commonly called the "Revised Version" (RV) or the "English Revised Version" (ERV) of 1881. This was a revision of the KJV made on the basis of the Greek texts of Westcott and Hort (1881) and Tregelles (1857) -- representing a departure from the Textus Receptus. The readings adopted by the committee of revisers were presented in a continuous Greek text in Palmer in 1881 which includes marginal notes showing every departure from the Greek text presumed to underlie the KJV (cf. Scrivener 1881).
This English Revised Version was the basis for the later American Standard Version (1901).
