Synopsis of the Four Gospels

This unique and useful resource includes a parallel comparison of the four Gospels in both the Greek Novum Testamentum Graece (NA27) and the English Revised Standard Version of the New Testament. The Greek text includes the full critical apparatus from the 26th edition of the Novum Testamentum Graece except for parallels from aprocryphal gospels and patristic sources.

The facing English text has an apparatus of significant variants in the AV (King James), RV, and RSV versions. [via]
