如何在字体更改后的段落后放置规则，而无需额外的垂直空间

Question

我正在为会议论文制作一个模板。这是一篇两栏文章，第一栏顶部有版权声明，下方紧接着一条水平线。这是一个最小的工作示例：

\documentclass[letterpaper,twocolumn,twoside,10pt]{article}
\title{Some sort of title}
\author{My name}
\date{}
\begin{document}
\maketitle

{\scriptsize
 Copyright 2018, held by some organization with a long name that will 
 invariably break over a single line.\hfill\break
 This paper was prepared for presentation at the foo
 59\textsuperscript{th} Annual Bar Baz Symposium held in London, UK, June
 20-26, 2018.\par}\rule{\linewidth}{0.5pt}

\section{Abstract}

More text that says something useful.

\end{document}

\par如果在较小的脚本块中没有，版权块中的行间距就会太大。如果使用\par，版权文本和规则下方就会多出一行间距。

据推测我应该能够覆盖版权块中段落后的间距，但我不确定如何做到这一点。

Answer 1

\documentclass[letterpaper,twocolumn,twoside,10pt]{article}
\title{Some sort of title}
\author{My name}
\date{}
\usepackage{calc}
\begin{document}
\maketitle

{\scriptsize
 Copyright 2018, held by some organization with a long name that will 
 invariably break over a single line.\hfill\break
 This paper was prepared for presentation at the foo
 59\textsuperscript{th} Annual Bar Baz Symposium held in London, UK, June
 20-26, 2018.\par}\vspace*{-.75\baselineskip}\noindent\rule{\linewidth}{0.5pt}

\section{Abstract}

More text that says something useful.

\end{document}

Answer 2

和tabularx：

\documentclass[letterpaper,twocolumn,twoside,10pt]{article}
\usepackage{tabularx, booktabs}

\title{Some sort of title}
\author{My name}
\date{}

\begin{document}

\maketitle

\noindent \begin{tabularx}{\linewidth}{@{}>{\scriptsize\arraybackslash}X@{}}%\scriptsize
 Copyright 2018, held by some organization with a long name that will
 invariably break over a single line. \\%%\hfill\break
 This paper was prepared for presentation at the foo
 59\textsuperscript{th} Annual Bar Baz Symposium held in London, UK, June
 20-26, 2018.\\
 \midrule
 \end{tabularx}%

\section{Abstract}

More text that says something useful.

\end{document}
