Different religious communities recognize different biblical canons. A few examples are:
(1) Samaritan tradition: the Samaritan Pentateuch.
(2) Judaism: the Tanakh, traditionally counted as 24 books and divided into Torah, Nevi’im (Prophets), and Ketuvim (Writings). The Mishnah, Talmuds, Mishneh Torah, and Shulchan Aruch are important Jewish religious works, but they are not part of the biblical canon.
(3) Eastern Orthodox traditions: Old Testament canons vary somewhat among the different Orthodox churches and generally include books beyond the Protestant Old Testament.
(4) Roman Catholic tradition: 46 Old Testament books and 27 New Testament books.
(5) Protestant traditions: generally 39 Old Testament books and 27 New Testament books, although some Protestant Bible editions also print the Apocrypha in a separate section.
(6) The Church of Jesus Christ of Latter-day Saints: the Bible together with the Book of Mormon, Doctrine and Covenants, and Pearl of Great Price.
(7) Other ancient Christian traditions: Syriac and Oriental Orthodox churches have their own canonical histories and should be considered individually rather than assigned a single universal book count.
Today, most biblical compilations comply with either the standards set forth by the British and Foreign Bible Society in 1825 which corresponds to the so-called Protestant Bible, or with one that includes the deuterocanonical books prescribed for so-called Catholic Bibles and the anagignoskomena for so-called Eastern / Greek Orthodox Bibles.

while I would add that the Eastern churches take the books of Maccabees far more seriouly than we do in the West
There are up to four of these additional books, and I am not sure how many the Armenian Orthodox accept but I think that it may be all four, Roman Catholics accept as canonical only two I think
