This book provides transcriptions and images of some of the oldest parchment manuscripts of the Gospel of John in Greek. It contains also a complete critical apparatus of all the parchment manuscripts of John, including such important manuscripts as Codex Vaticanus and Codex Sinaiticus. The transcriptions and plates are restricted to fragmentary and difficult-to-read copies. These havereceived the same detailed treatment as was used by the International Greek New Testament Project to make an edition of the papyri of John (Brill: 1995). The International Greek New Testament Project is a European-American project currently collaborating with the Institut für neutestamentliche Textforschung (Münster, Germany) to make a critical edition of the Gospel of John in the Editio Critica Maior.
