If you're running Debian or Ubuntu, install the texlive-publishers package. The template is called elsarticle.
Two-column layout is an option:
\documentclass[twocolumn]{elsarticle}
For the keywords, you need to define
\begin{keywords}
keywords go here
\end{keywords}
As the combine is better documented, here are an example of a volume journal with a few articles using the paper class with cover and a table of contents of articles.
Indeed the cover is simple, the first article start in even page, there are not fancy headers, etc. but is only a minimal working example to show how to join articles in a volume, right? Anything else is left as exercise to the reader. ;)
Output of pages 1-2:
\documentclass[journal,noindent,headline]{paper}
\usepackage[rmargin=1.5cm]{geometry}
\usepackage[english,latin]{babel}
\usepackage{microtype}
\usepackage{xcolor}
\usepackage{lipsum} % for dummy text only
\usepackage[colorlinks,linkcolor=blue!50!black]{hyperref}

Note: I have done that MWE in a single file but in practice you may want maintain the contents of each article in child documents. To construct a MWE with child document cut from % ARTICLE 1 until % ARTICLE 2, save it as article1.tex, and replace this chunk of text by \input{article1} or \include{article1} (there are no difference in this case). If you want render single articles, use \includeonly or see the docmute package to maintain child documents as complete LaTeX files.
Reminder: Do not forget check look also the combine class.

One thing to look at is latexdiff. Here's the description from CTAN:
