如您所见，第 10 项被拆分到两个页面。如何防止这种情况并强制 bibitem 出现在单个页面上？
别误会我的意思。我的目标不是将所有内容都放在一页上。我只是不喜欢我的参考书目中有破碎的实体。
答案1
请注意，@egreg 提出的解决方案正是您所要求的。但是，您可能需要重新考虑这是否真的是您想要的应该要求。如果书目条目跨越 4、5 甚至（颤抖）更多行怎么办？在这种情况下，您是否仍想禁止任何换行符，冒着创建可怕的未满页面的风险？或者，您只想告诉 LaTeX 不要在参考书目中创建“孤行”（页面底部的单行）或“寡行”（页面顶部的单行）？避免创建印刷孤行和孤行可能是一个更合理的目标。
不幸的是（在我看来），主要的 LaTeX 文档类为环境设置了和的thebibliography相当宽松的设置。这些参数用于为排版“寡妇”和“孤儿”（后者在 TeX 术语中称为“俱乐部”）分配惩罚。幸运的是，可以使用包的命令轻松将这些惩罚更改为——功能上等同于“无穷大” ：\widowpenalty\clubpenalty400010000etoolbox\AtBeginEnvironment
\usepackage{etoolbox}
\makeatletter
\AtBeginEnvironment{thebibliography}{%
\clubpenalty10000
\@clubpenalty \clubpenalty
\widowpenalty10000}
\makeatother
在您的序言中添加此内容后，您的参考书目的第 10 条条目（以及任何其他由 3 行或更少行组成的条目）将不再分布在两页上。
顺便说一句，如果您的需求是一次性的，您甚至不需要担心包裹。只需在第一条指令etoolbox之后和之前包含以下指令：\begin{thebibliography}{99}\bibitem
\makeatletter
\clubpenalty10000
\@clubpenalty \clubpenalty
\widowpenalty10000
\makeatother
答案2
只需\interlinepenalty=10000添加\begin{thebibliography}：
\begin{thebibliography}{99}
\interlinepenalty=10000
\bibitem{1}John Doe, Jane Doe, Captain America, Superman:
\emph{Bibliography item with a very long title: part one},
Some title of a magazine with a very long title, 2009, pages 1234--4321
...
\end{thebibliography}
这会阻止段落内的分页。
