# [Tex/LaTex] How to write abstract and acknowledgement in book format

abstractacknowledgementsbook-designbooks

I need to use this: \documentclass[a4paper,11pt]{book}

I have a main.tex file that organizes all the chapters. There is \frontmatter. In the frontmatter, there is

    \include{acknowledgement }
\include{abstract}
\include{dedication}


So, I created 3 files with this name. It kind of works. BUT it does not look like real abstract, ack… or dedication page.

I tried similar to

    \begin{abstract}
My text
\end{abstract}


It did not work. Can you please point me, how to add, abstract, dedication, acknowledgment?

A few weeks ago I tried to add a dedication and an abstract to my book-document and this is what I found on the net and adapted:

dedication.tex

\thispagestyle{empty}
\null\vspace{\stretch {1}}
\begin{flushright}
This is the Dedication.
\end{flushright}
\vspace{\stretch{2}}\null


abstract.tex

\newenvironment{abstract}%
{\cleardoublepage\thispagestyle{empty}\null\vfill\begin{center}%
\bfseries\abstractname\end{center}}%
{\vfill\null}
\begin{abstract}
This is the abstract.
\end{abstract}


acknowledgements.tex

\newenvironment{acknowledgements}%
{\cleardoublepage\thispagestyle{empty}\null\vfill\begin{center}%
\bfseries Acknowledgements\end{center}}%
{\vfill\null}
\begin{acknowledgements}
These are the acknowledgements.
\end{acknowledgements}


main-file.tex

\frontmatter
\include{content/frontmatter/titlepage}
\include{content/frontmatter/dedication}
\include{content/frontmatter/abstract}
\include{content/frontmatter/acknowledgements}
\include{content/frontmatter/preface}
\tableofcontents
... and so on ...
