No, that's just the first one you know about. And what in the world does it matter how and when the letters of scripture were bound? Peter himself acknowledged the letters of Paul were scripture.
“No, that’s just the first one you know about.”
Then provide evidence for an earlier version.
“And what in the world does it matter how and when the letters of scripture were bound?”
Again, read up on Marcion. Marcion is substantial evidence that there did not exist a canon in Apostolic times. Sure, Peter acknowledges that Paul’s writings are authoritative, but he never says, “these writings of Paul’s are authoritative.” He never specifies which ones.
