The International Greek New Testament Project (IGNTP) began in 1926 as a cooperative enterprise between British and German scholars to establish a new critical edition of the New Testament. Early results of the work were critical apparatus of the Gospel of Matthew and the Gospel of Mark produced by S. C. E. Legg in the 1930s. Wartime difficulties prevented cooperation during most of the 1940s, but the project was resurrected in 1949 as a cooperative endeavour between British and North American scholars. In the meantime research was taken up by Kurt Aland and the Institut für neutestamentliche Textforschung in Münster. British and North American cooperation resulted in the publication of a critical apparatus for the Gospel of Luke in the 1980s.
