# Start a specific chapter on the left page?

Using the `book` class with the `twoside` option, I get chapters that start on right/odd pages, which is the expected behavior.

Still, I would like to have some specific chapters starting on a left/even page. Is there a way to achieve this?

## 1 Answer

the `book` class provides the `openright` switch, which is "on" by default. if you want to have a chapter start on the left, just before the `\chapter` command, insert

``````\makeatletter
\@openrightfalse
\makeatother
``````

make sure this is in the same file as the `\chapter` command. if the chapter is in a separate file, accessed by `\include`, and the "don't open right" code is in the main file before the `\include`, the code will be delayed until after the `\include`d file has been read and processed.

to reset the right-opening mode, do just the opposite:

``````\makeatletter
\@openrighttrue
\makeatother
``````

this can be made into a pair of commands, perhaps `\OpenLeft` and `\OpenRight`.

• N.B. as stated at the beginning of the answer, the first code block just turns the default off. Hence, calling it `\OpenLeft` might be a bit confusing, because it makes the chapter open anywhere, not specifically on the "left". – Sparhawk Jun 27 '17 at 5:25
