I would like to move some preliminary stuff, i.e. abstract and acknowledgments, before the table of contents. By default, the TOC comes right after the title page. I am aware of the solution to include abstract into the YAML header like so, but that does not seem flexible enough for multiple things to come before the TOC.
Note a similar question here, which only refers to HTML.
My current YAML header:
title: "Title" subtitle: "Subtitle" author: - "Institution" - "Name" date: "September 2020" output: bookdown::pdf_book: includes: in_header: preamble.tex keep_tex: yes latex_engine: xelatex citation_package: natbib fontsize: 12pt linestretch: 1.5 toc-depth: 2 secnumdepth: 2 lof: True lot: True site: bookdown::bookdown_site documentclass: book bibliography: ["references.bib"] csl: american-political-science-association.csl geometry: "left=2.5cm, right=2.5cm, top=2.5cm, bottom=2.5cm"
