So the Apocrypha is a collection of writings generally believed to have been written during the Second Temple Era -- after the Old Testament and prior to the New Testament.
You will find three ways in which the Apocrypha is printed in bibles today:
1) they are given their own section called "Apocrypha," following a tradition started by Martin Luther in treating these works as separate from the Old Testament;
2) they are put together with the Old Testament, following the traditions of the early translations of the Bible;
3) rarely, you will find a Bible that does not include some or all of the Apocrypha, following traditions that do not consider Apocrypha a valid part of canon. Additionally, Jewish bibles leave out not only the New Testament, but the Apocrypha as well.
