If this is something that interests you, the recent book Meetings with Remarkable Manuscripts is very good. This book is not covered, but the Codex Amiatinus also mentioned in the article is.
Personally, I'd call what came out of the Nag Hammadi remarkable. Another edge case that I'm reading is The Kolbrin (it's authenticity is in question, but it's words are very inspiring) [0]
And of course, the Pistis Sophia, whose opening line is:
"IT came to pass, when Jesus had risen from the dead, that he passed eleven years discoursing with his disciples, and instructing them..." [1] [2]
The first few chapters are full of hard to read symbolism, but there's a lot to absorb in there.
In case it's not obvious, the book in the photo at the top of the article is NOT the St. Cuthbert Gospel. (You don't hold a thousand-year-old book in your bare hand.)

The book in the article is approximately 70 to 100 years older than the Book of Kells. There are many books that are even older. What makes this one special is that it has not been rebound, as the Book of Kells and most medieval codices have been.
