Formatting endnotes resp. references

Question

I refer to https://tex.stackexchange.com/a/100001/113820 formatting endnotes. How to get endnotes left aligned (without indent of first numbered line with [1], [2] etc.)

Answer 1

You can modify the redefinition of \makeenmark to produce a left flush label in the indentation space:

\documentclass{article}
\usepackage{endnotes,etoolbox}

\renewcommand{\notesname}{References}

% end note marker = superscripted number in brackets
\renewcommand\makeenmark{\textsuperscript{[\theenmark]}}

% in the endnotes, we change it without `\textsuperscript`, adding a space
\patchcmd{\theendnotes}
  {\makeatletter}
  {\makeatletter\renewcommand\makeenmark{\makebox[\parindent][l]{[\theenmark]}}}
  {}{}
