[Tex/LaTex] Remove blank page after TOC and title page

blank-pagetable of contentstitles

I am using the book document class and want to remove the blank pages it is adding after my title and after my TOC. I don't care to have any blank pages in this whole document actually, however these are the two places where blanks are present right now. I have tried to redefine /cleardoublepage as many Stackoverflow answers suggested, but I still see the new pages present and feel like I must be doing something wrong or missing a package.

Here is what my setup looks like currently for my tex:

\documentclass[12pt,oneside,openany]{book}

\usepackage[utf8]{inputenc}
\usepackage[margin=1in,includeheadfoot,asymmetric]{geometry}
\usepackage{makeidx}

\usepackage{fancyhdr}
\pagestyle{fancy}
\rhead{Assignment}
\lhead{}

\title{Assignment}
\author{Person One \and Person 2}

\begin{document}

\begingroup
\let\cleardoublepage\relax
\let\clearpage\relax  
\maketitle
\endgroup

\frontmatter
\begingroup
\let\cleardoublepage\relax
\let\clearpage\relax
\tableofcontents
\endgroup


\mainmatter

\chapter{Report}

\end{document}

Best Answer

The extra page is generated by \chapter which is outside the group where \cleardoublepage was redefined.

\documentclass[12pt,oneside,openany]{book}

\usepackage[utf8]{inputenc}
\usepackage[margin=1in,includeheadfoot,asymmetric]{geometry}
\usepackage{makeidx}

\usepackage{fancyhdr}
\pagestyle{fancy}
\rhead{Assignment}
\lhead{}

\title{Assignment}
\author{Person One \and Person 2}

\let\cleardoublepage=\clearpage

\begin{document}

\maketitle

\frontmatter
\tableofcontents

\mainmatter

\chapter{Report}

\end{document}

A somewhat safer options is to use report class and play with the page numbers directly.

\documentclass[12pt,oneside,openany]{report}

\usepackage[utf8]{inputenc}
\usepackage[margin=1in,includeheadfoot,asymmetric]{geometry}
\usepackage{makeidx}

\usepackage{fancyhdr}
\pagestyle{fancy}
\rhead{Assignment}
\lhead{}

\title{Assignment}
\author{Person One \and Person 2}

\begin{document}
\maketitle

\clearpage
\renewcommand{\thepage}{\roman{page}}
\setcounter{page}{1}

\tableofcontents

\clearpage
\renewcommand{\thepage}{\arabic{page}}
\setcounter{page}{1}

\chapter{Report}

\end{document}
