# Second part of abstract is not numberred (lineno with elsarticle)

I need to insert line numbers in elsarticle, so I added:

\usepackage{lineno} % add
\linenumbers


in the article preamble.

However, I noticed that part of abstract is not numbered:

Could you suggest what should I change, please?

My document looks as as follows:

\documentclass[review]{elsarticle}
\usepackage[hyphens]{url}
\linenumbers
\providecommand{\tightlist}{%
\setlength{\itemsep}{0pt}\setlength{\parskip}{0pt}}

From the lineno documentation:

\linenumbers takes effect only when a paragraph is finished. This is important if you use \linenumbers for a single paragraph only. This will not work

In order to get the correct line numbering you can either explicitly end the paragraph

\documentclass[review]{elsarticle}

\usepackage{lineno}

\begin{document}

\linenumbers

\begin{frontmatter}
\title{Title}
\author{Me}
\begin{abstract}
First line of abstract. This part of abstract is numbered as well
as other sections. Only the second part of abstract is not numbered.

The second part of the abstract. Lorem ipsum dolor sit et amet.
Some text.\par% or add an empty line after this one
\end{abstract}
\end{frontmatter}

\section{Introduction}\label{introduction}
Some text

\end{document}


or use the linenumbers environment

\documentclass[review]{elsarticle}

\usepackage{lineno}

\begin{document}

\linenumbers

\begin{frontmatter}
\title{Title}
\author{Me}
\begin{abstract}
\begin{linenumbers}
First line of abstract. This part of abstract is numbered as well
as other sections. Only the second part of abstract is not numbered.

The second part of the abstract. Lorem ipsum dolor sit et amet.
Some text.
\end{linenumbers}
\end{abstract}
\end{frontmatter}

\section{Introduction}\label{introduction}
Some text

\end{document}

• Thank you, adding \par at the end of second paragraph resolved my issue. – matandked Feb 28 '17 at 16:38
