It’s the copy you hold in your hands. That one. Though yours may or may not have the complete canon of 73 books. The Holy Spirit guided the Catholic Church (capital C) in canonizing the table of contents for Sacred Scripture. There was not “official bible” before this. So what did Christians do for 300+ years after Christ? They didn’t (indeed, they couldn’t) read their bible. What they did was go to Mass on Sundays. All well documented in the Didache (50-90 AD)
One would think that they would have made a couple-few editions of their "Bible". Maybe they did but were lost? The earliest known Bible of which I'm aware was made by King James, but I presume that there are lesser known Bibles that had already been created.
