My new article on "Manuscripts of the Lord's Prayer" has just been published on the Bible Odyssey, a website developed and maintained by Society of Biblical Literature. On the Bible Odyssey, biblical scholars "share the latest historical and literary research on key people, places, and passages of the Bible."This was my second entry – I have written a piece on the "Alexandrian Text"last year. You can find a fuller report on the Odyssey project in that blogpost.
There are various other entries related to textual criticism, and, under "tools" you can find a special timeline on the history of the text of the New Testament. Go on and explore!
