Well, a long ways back i looked at my Bible and i looked in my cousin's Bible and found that my Bible had books missing in it. My cousin is Catholic. Can someone explain why Bibles like the NKJV have books missing from it?
Some books have not been included in the approved canon. The NKJV is an approved version. Some bibles have the apocrapha (spelling) included. Usually between the old and new testiment.

What is your Bible and what is your cousin's. It sounds as though, despite being Catholic, your cousin is actually using a Protestant Bible. That's the only way I can imagine that your Bible could have more books than his. I suspect that you are using something like the original KJV (with 'apocrypha') and he is using an NKJV without (you can also get them with 'apocrypha'). What books exactly do you think are missing? The reason some Old Testaments are shorter than others is that the Deuterocanonical books (OT 'apocrypha') are wholly or partially excluded. The earliest OT of the Church was the entire Septuagint. This is the OT still used by the Orthodox Church and is the longest. At some later date Rome slightly reduced their canon, though it remains almost as large as the Orthodox one. They also reorganised and renamed some of the books. Some time after the Reformation, the reformers decided, unilaterally, that the Deuterocanonical texts were uninspired and ditched the lot. This didn't happen straight away, however, which is why the 1611 KJV included these books (or at least as many as are included in the RC canon).
If you have the NKJV it must be a version with apocrypha if it has more books than your cousin's. If your cousin's Bible doen't have the 'apocrypha' (Deuterocanonical OT texts) then it isn't a Roman Catholic Bible. The only books that were ever dropped from the RC canon were a few of the OT books (3 and 4 Maccabees, for instance) that are still used by the Orthodox Church but, to my knowledge, you cannot get an NKJV with the complete Septuagint canon (in fact, I don't believe there is an English Bible with the full set of books at all - there will be when the Orthodox Study Bible comes out, though). Which books do you think are missing from the RC Bible? I'm afraid that as far as I can see, you must be misremembering. It was the Protestants who removed large numbers of books, not the RCC.
