How do I remove blank pages coming between two chapters in Appendix?

Question

Is there a way to remove blank pages appearing between two chapters, in Appendix?

Answer 1

One thing I discovered is that using the \include command will often insert and extra blank page. Riffing on the previous trick with the \let command, I inserted \let\include\input near the beginning of the document, and that got rid of most of the excessive blank pages.
