Text Criticism Resources Online

Introduction

• Introduction to Textual Criticism and Encyclopedia of New Testament Textual Criticism - Start with these for an overview
• Interpreting Ancient Manuscripts - Very helpful with some good exercises
• The Development of the NT Text - A very nice site now archived (Note, however, that the author wants to argue for more credibility--or at least attention--given to the "Byzantine" text type than most scholars would grant it.)
• Basic Principles of Textual Criticism (brief)
• Canons of Criticism (more comprehensive)
• A Student's Guide to NT Textual Variants - Check the brief introduction, but more helpful may be the extended comments in 'plain English'  

Manuscript Descriptions: 

• Papyri 
• Uncials 
• Minuscules:  1-500  501-1000  1001-1500  1501-2000  2001 and up

Organization of Mss and Families

• Greek Manuscript Evidence - Helpful tables identifying the most important mss.
• Chart of Families and Mss - Another good table; lists many more mss but with less info

Texts Highlighting Mss Differences

• Biblon 2000 Greek New Testament - for portions of NT, first online Greek NT with critical apparatus
• HTML Bible Index - Greek New Testament - Can at least highlight differences between Textus Receptus, Byzantine, and Alexandrian texts
• Stuttgart Electronic Study Bible - This is the first digital edition of a critical text, but it will cost you $280.

Text Critical Commentaries

• Wieland Willker - TCG 2004 An Online Textual Commentary on the Greek Gospels - I recommend that you download the PDF files from this excellent site, especially The Best MSS of the Gospels and the commentaries on each of the Gospels
• NET Bible - Be sure to check the notes in this excellent online and freely downloadable Bible
