That is, seven books, and parts of two more (Esther and Daniel).
All the books of the Bible, all bibles, are there because the Catholic church weeded through all the written works that were floating out there during those times and made cross references to what did not concur with Apostalic Tradition. If what was written did not agree with Apostalic Tradition it wasn't put in the Bible. So I would have to say that, like it or not, Sola Scriptura is based on Catholic Tradition.
