I am using the IEEE template in Overleaf and it show a indentation after the ninth reference at the first line as demonstrated below

enter image description here

Here is the documentclass and packages that I exploited

\documentclass[journal]{IEEEtran}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{subfigure}
\usepackage{graphicx}
\usepackage{multirow}
%\usepackage{caption2}
\usepackage{booktabs}
\usepackage{makecell}
\usepackage{cite}
\usepackage{array}
\usepackage{caption}
\usepackage{supertabular}
\usepackage{color}

Meanwhile, I wrote the references at the end of the manuscript as

Change \begin{thebibliography}{1} to \begin{thebibliography}{99}.

The parameter after the \begin{thebibliography} command defines how much space to reserve for the number of labels. {99} tells LaTeX to expect that none of the bibliography item numbers will be wider than the number 99.

  • Really thanks! It works!

  • Hi, could you add to your answer a short explanation as to why this solves the problem? What does the second input do?

  • @EladDen the number in the environment argument is supposed to be the largest (in sense of width) number used in the list; it is used to calculate the amount of indentation.
