The 66 books of the Bible, in order.

The Protestant Bible has 66 books — 39 in the Old Testament and 27 in the New Testament. The Catholic Bible includes 7 additional Old Testament books (the Deuterocanon: Tobit, Judith, Wisdom, Sirach, Baruch, 1 Maccabees, 2 Maccabees) for a total of 73. Eastern Orthodox Bibles add a few more (3 and sometimes 4 Maccabees, Psalm 151) for 76 or 78. This tool follows the 66-book Protestant canon.

The labels refer to length, not importance. The five Major Prophets (Isaiah, Jeremiah, Lamentations, Ezekiel, Daniel) are long books. The twelve Minor Prophets (Hosea through Malachi) are short — most just a few chapters. All seventeen are equally inspired; the distinction is purely about how much text each occupies.

Lamentations is short — only five poetic chapters mourning Jerusalem's destruction in 586 BC — but tradition attributes it to Jeremiah, so it's placed between Jeremiah and Ezekiel rather than with the Minor Prophets.

The Gospels: Matthew, Mark, Luke, John. Four names, one type of book (narrative accounts of Jesus's life), and they're the most familiar to most readers. After that the Pentateuch (Genesis, Exodus, Leviticus, Numbers, Deuteronomy) is next — five books that tell one continuous story from creation through the death of Moses.

Yes — the Hebrew Bible groups the same Old Testament books into three sections: Torah (the first five), Prophets (Joshua through Malachi but including Samuel, Kings, and the Twelve as units), and Writings (Psalms, Job, Proverbs, the Megillot, Daniel, Ezra-Nehemiah, Chronicles). It ends with Chronicles rather than Malachi. The content is the same; the order and grouping differ.
