我想在参考书目的开头添加指向目录的超链接：
我的（显而易见的）方法是：
\documentclass[letterpaper,11pt]{book}
\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage{hyperref}
\title{How do I add a hyperlink in thebibliography to the table of contents?}
\begin{document}
\frontmatter
\maketitle
% this is the hypertarget I want to put in thebibliography
\addtocontents{toc}{\protect\hypertarget{toc}{}}
\tableofcontents
\mainmatter
\chapter{Chapter 1}
I cite authors and books: \cite{author1,book1}.
\begin{thebibliography}{}
%Here I want the hyperlink to the table of contents,
%but if I don't know how to do it without getting an error:
%\hyperlink{toc}{Hyperlink back to table of contents.}
\bibitem{author1}
This is the info of citation 1.
\bibitem{book1}
This is the info of citation 2.
\end{thebibliography}
\end{document}
使用
\bibitem{whatever} \hyperlink{toc}{Hyperlink back to table of contents.}
\bibitem{author1}
This is the info of citation 1.
\bibitem{book1}
This is the info of citation 2.
作品：
但我不知道如何删除该号码（我尝试搜索该方法但没有找到任何东西）。
我在论坛上看到过类似的问题，但它们只会让我更加困惑，因为我没有看到任何人问这个特定的任务。不过，如果这是一个重复的问题，我很抱歉，我以为这很简单，但我很难找到所需的超链接。

您可以将超链接添加为\bibname和 的一部分\contentsname。
\documentclass[letterpaper,11pt]{book}
\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage{hyperref}
\usepackage{etoolbox}
\title{How do I add a hyperlink in thebibliography to the table of contents?}
\let\oldcontentsname=\contentsname
\patchcmd{\tableofcontents}{\MakeUppercase\contentsname}{\MakeUppercase\oldcontentsname}{}{FAILED}
\let\oldbibname=\bibname
\patchcmd{\thebibliography}{\MakeUppercase\bibname}{\MakeUppercase\oldbibname}{}{FAILED}
\begin{document}
\frontmatter
\maketitle
\def\contentsname{\protect\hypertarget{toc}{\oldcontentsname}\par
\protect\hyperlink{bib}{\Large Hyperlink to bibliography.}}
\tableofcontents
\mainmatter
\chapter{Chapter 1}
I cite authors and books: \cite{author1,book1}.
\def\bibname{\protect\hypertarget{bib}{\oldbibname}\par
\protect\hyperlink{toc}{\Large Hyperlink to table of contents.}}
\begin{thebibliography}{}
\bibitem{author1}
This is the info of citation 1.
\bibitem{book1}
This is the info of citation 2.
