Answer:
The KJV Bible is made up of 2 sections: The Old Testament and the New Testament. The entire Protestant Bible is made up of 66 Books from Genesis to Revelation. The first five books of the Bible are known as the Pentateuch. "Penta" meaning "5" and "teuch" meaning book(s). So it is reasonable to think that all books of the Bible are actually considered books.
Old Testament
Genesis Exodus Leviticus Numbers Deuteronomy Joshua Judges Ruth 1 Samuel 2 Samuel 1 Kings 2 Kings 1 Chronicles 2 Chronicles Ezra Nehemiah Esther Job Psalms Proverbs Ecclesiastes Song of Solomon Isaiah Jeremiah Lamentations Ezekiel Daniel Hosea Joel Amos Obadiah Jonah Micah Nahum Habakkuk Zephaniah Haggai Zechariah Malachi
New Testament
Matthew Mark Luke John Acts Romans 1 Corinthians 2 Corinthians Galatians Ephesians Philippians Colossians 1 Thessalonians 2 Thessalonians 1 Timothy 2 Timothy Titus Philemon Hebrews James 1 Peter 2 Peter 1 John 2 John 3 John Jude Revelation
Additionally
The original 1611 King James Bible included an Apocrypha section which included the deuterocanonical books (Judith, Tolbit, Maccabees, etc.) that are in Catholic bibles but have since been removed from Protestant bibles. There is a long standing debate between Catholics and Protestants on the inclusion of these books in the Bible.
