I am currently trying to type up a literature review for a class where I have to use the citation style which is relevant to my field. I would like to be able to put the citation I am talking about and the analysis of the source under it with a final bibliography at the end of the paper. Everything seems to work okay and the citations are the way I want them formatted, but at the top of my first page a list of in-text citations for all of my sources appears.

I have seen some notes about nocite{*}, but it doesn't seem to make any changes in my document.

My preamble looks like this,

documentclass[12pt,letterpaper]{article}% 

Set margins to 1.5in

usepackage[margin=0.75in]{geometry}



% for crimson text

usepackage{crimson}

usepackage[T1]{fontenc}



% setup parameter indentation

setlength{parindent}{15pt}

setlength{parskip}{6pt}



% for 1.15 spacing between text

renewcommand{baselinestretch}{1.15}



% For defining spacing between headers

usepackage{titlesec}

% Level 1

titleformat{section}

  {normalfontfontsize{18}{0}bfseries}{thesection}{1em}{}

% Level 2

titleformat{subsection}

  {normalfontfontsize{14}{0}bfseries}{thesection}{1em}{}

% Level 3

titleformat{subsubsection}

  {normalfontfontsize{12}{0}bfseries}{thesection}{1em}{}

% Level 4

titleformat{paragraph}

  {normalfontfontsize{12}{0}bfseriesitshape}{theparagraph}{1em}{}

% Level 5

titleformat{subparagraph}

  {normalfontfontsize{12}{0}itshape}{theparagraph}{1em}{}

% Level 6

makeatletter

newcounter{subsubparagraph}[subparagraph]

renewcommandthesubsubparagraph{%

  thesubparagraph.@arabicc@subsubparagraph}

newcommandsubsubparagraph{%

  @startsection{subsubparagraph}    % counter

    {6}                              % level

    {parindent}                     % indent

    {12pt} % beforeskip

    {6pt}                           % afterskip

    {normalfontfontsize{12}{0}}}

newcommandl@subsubparagraph{@dottedtocline{6}{10em}{5em}}

newcommand{subsubparagraphmark}[1]{}

makeatother

titlespacing*{section}{0pt}{12pt}{6pt}

titlespacing*{subsection}{0pt}{12pt}{6pt}

titlespacing*{subsubsection}{0pt}{12pt}{6pt}

titlespacing*{paragraph}{0pt}{12pt}{6pt}

titlespacing*{subparagraph}{0pt}{12pt}{6pt}

titlespacing*{subsubparagraph}{0pt}{12pt}{6pt}



% Set caption to correct size and location

usepackage[tableposition=top, figureposition=bottom, font=footnotesize, labelfont=bf]{caption}



% set page number location

usepackage{fancyhdr}

fancyhf{} % clear all header and footers

renewcommand{headrulewidth}{0pt} % remove the header rule

rhead{thepage}

pagestyle{fancy}



% Overwrite Title

makeatletter

renewcommand{maketitle}{bgroup

   begin{center}

   textbf{{fontsize{18pt}{20}selectfont @title}}\

   vspace{10pt}

   {fontsize{12pt}{0}selectfont @author} 

   end{center}

}

makeatother



% For full citations inline

usepackage{bibentry}

nobibliography*



% For making hanging indents under citations

usepackage{hanging}

newcommandhangbibentry[1]{%

    smallskipparhangpara{1em}{1}bibentry{#1}smallskippar %{indent}{afterline}

}



% For indenting the first paragraph of every line

usepackage{indentfirst}



% For use of astron citation package

usepackage{natbib} 

And this is what I have right before I end the document.

bibliographystyle{astron}

bibliography{mnemonic.bib,bibtemp.bib}

This is an example of how I call the bibliography:

subsection*{hangbibentry{Mamajek2008ImprovedDiagnostics}}

Any ideas on how to fix this?
