The AMS suggests to remove a TOC entry from an amsart document by suppressing the entry just before it is to be added to the TOC.

Their solution works without the biblatex package loaded. However, when I load the biblatex package, it fails, and that TOC entry is still printed even with the skip command. Please see the below MWE demonstrating the problem.

\documentclass{amsart}
% \usepackage{biblatex} %uncomment to see difference
\DeclareRobustCommand{\SkipTocEntry}[4]{}
\begin{document}
\tableofcontents
\addtocontents{toc}{\SkipTocEntry}
\section{First}
\end{document}

Notice that it is not necessary to use biber in the compilation to demonstrate the issue. Using pdflatex on the document alone shows the difference.

    If you load biblatex you need to gobble more in the .toc file, since biblatex writes some commands to that file. \DeclareRobustCommand{\SkipTocEntry}[8]{} works. – moewe Jan 05 '20 at 17:45

  • @moewe, that led me to the solution. Gobbling more of the TOC line did exactly what I needed. Would you like to write up the answer so that I can credit you for it? – Jason Hemann Jan 05 '20 at 18:14

As discussed at length in Why does biblatex produce `defcounter` lines in .toc?, biblatex adds additional content to the .toc file. So when you load it you get

\defcounter {refsection}{0}\relax 
\contentsline {section}{\tocsection {}{1}{First}}{1}%

instead of just

\contentsline {section}{\tocsection {}{1}{First}}{1}%

Hence, if you want to gobble the line, you need to gobble more.

\documentclass{amsart}
\usepackage{biblatex} %uncomment to see difference
\DeclareRobustCommand{\SkipTocEntry}[8]{}
\begin{document}
\tableofcontents
\addtocontents{toc}{\SkipTocEntry}
\section{First}
\end{document}

If you load hyperref you need to gobble even more, because the argument structure changes.
