Is This a Fix Up Novel?

The book is a fix up of three novellas that were published between 1955 and 1957. Walter Miller took them and sort of rewrote them and put them together to make one book. The theme was this cyclic nature of history and how mankind repeats the same mistakes over and over. And so, you know, I enjoyed parts of it more this time, but other parts of it, I had some issues with which we can get into.
