The Book of Isaiah is one book in the Bible. Scholars tell us that there are at least two parts to Isaiah, Chapters 1-39 which come from the time of the prophet Isaiah (742-701 BCE) and chapters 40-66, referred to as second Isaiah which come from the time just before the fall of Babylon to the Persian king Cyrus in October 539 BCE  and the following generation. Some scholars would divide Isaiah into three parts with chapters 56-66 as Third Isaiah from 530-510 BCE.

You can read a general introduction to Isaiah and first Isaiah, here. Generally speaking, First Isaiah is concerned with the time of punishment and anticipates the restoration. Second Isaiah assumes the time of restoration is at hand. Both parts of Isaiah assume that the entire world should recognize God as sovereign.

While Second Isaiah is later than First Isaiah, and has a different author, notice what both authors hold in common as we read.
