Editio Octava Critica Maior is a critical edition of the Greek New Testament produced by Constantin von Tischendorf.
The edition was accompanied by a rich critical apparatus in which he assembled all of the variant readings that he or his predecessors had found in manuscripts, versions, and fathers.
[7] Tischendorf's Editio Octava and The New Testament in the Original Greek of Westcott and Hort were sufficient to make the Textus Receptus obsolete for the scholarly world.
[9] Nestle used Editio octava in his Novum Testamentum Graece for its extensive representation of the manuscript tradition and Westcott-Hort's text for its development of the methodology of the textual criticism.
[10] Nestle called Tischendorf's edition "the most complete survey of what has been done on the Greek New Testament up to the present time".
