General ⇒ Extra page in non-numbered chapter

[Jongomez]

In my "book" class document I am using for non- numbered chapter:

tableofcontents

\chapter*{Introducción}
\markright{\MakeUppercase{Introducción}}
\addcontentsline{toc}{chapter}{Introducción}
\input{sections.tex/Introducción}

That works ok for the header. BUT before the page "Introducción" with its corresponding text: Prefacio bla..bla..bla, I get en EXTRA-PAGE which only contains the title "Introducción".

Note.- I have also proved with the command "\include{sections.tex/Inroducción}", instead of \input{sections.tex/Introducción}, but the result is the same with the extra-page.
Can anyone let me know how to eliminate the extra-page.

Thank you for your help.

Hi Jon,

by default, a book class document starts chapters on right-hand pages. So, an empty page may be inserted to achieve this.

To change this, you can set the openany option.
