In using Elsevier class, I would like to insert an extra line of

DOI: 10.xxxxx/blah

right after the Keywords part.

What I did is to type this line after the block \begin{keyword} ... \end{keyword} as a standard (regular) text. But the string I wanted to insert (e.g. DOI: 10.xxxxx/blah) appears, not after the Keywords part as intended, but in the first page separately.

Please help me to resolve this problem. Thank you very much in advance.

    Does tex.stackexchange.com/questions/154213 help? If not, a minimal example of how you use the elsarticle class is needed. – egreg May 5 '18 at 10:02
  • Great! Thank you for you hint, I found helpful information from the link you gave. – Thanh Nguyen May 5 '18 at 13:14
  • How could I adapt this solution to add extra information (like “Article history: Received ..., Revised ..., Accepted ...”) right after the Address field, and outside of the two hrule for the Abstract part? I put \begin{extrainfo} \begin{center} \textbf{Article history}\\ blah blah\\ \end{center} \end{extrainfo} after the last \address[]{} command, and before the block \begin{abstract} ...\end{abstract}, but it failed to work. Thank you in advance. – Thanh Nguyen May 5 '18 at 15:31

You can use the ideas in https://tex.stackexchange.com/a/154216/4427

\documentclass[preprint, authoryear]{elsarticle}


% patch \maketitle to accommodate the new information before the first rule
% patch \maketitle to accommodate the DOI after the keywords
  {\fi\hrule}% the second rule

% an environment for the new information
  {\global\setbox\extrainfobox=\vbox\bgroup\parindent=0pt }

% The DOI
  \gdef\@DOI{DOI: #1}%
\let\@DOI\@empty % initialize





\address{Address for correspondance:}





\textbf{Article history}

blah blah
