for my thesis i decided to improve my work inserting directly in Lyx the command "\appendix" but i don't understand how to end this part. I would like to insert an Appendix between two different chapters but if i use this command everything i'll write after that will be inside the Appendix without the possibility to come back to a "normal chapter". Could someone help me? Could someone explain me how to end the \appendix part? Thanks a lot!!

You can use the appendix package:

\documentclass{book} % or report or ...
\section{An appendix}
\section{Another appendix}

Read the manual (> texdoc appendix) for more information.

  • @TanjaSantner My apologies, I made a typo. It should be \begin{subappendices} and \end{subappendices}. I have corrected my answer. Oct 8, 2018 at 18:12

This new command \noappendix should work, at least with a manual set up.

  \setcounter{chapter}{2}% <--manually insert the number of chapters before \appendix was used
  • Thank you for your answering my question. I tried what you told me to do, but the chapter after my "Appendix" still still appears as an appendix. Oct 7, 2018 at 19:59
  • Did you put the code on preamble and then \noappendix just before start the new chapter?
