biblatex - Ibid on following page

Question

I organize my source with biblatex (version 3.8, BibTeX backend) and got everything setup. This is my preamble:

\documentclass[12pt]{report}
\usepackage[utf8]{inputenc}
\usepackage{mathptmx}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
\usepackage{geometry}
\usepackage[expansion, final]{microtype}
\usepackage[style=verbose-ibid, backend=bibtex, dashed=false]{biblatex}
\usepackage{csquotes}
\usepackage{setspace}

% Style Setup
\geometry{a4paper, top=25mm, left=25mm, right=40mm, bottom=25mm}
\setstretch{1.5}
\interfootnotelinepenalty=10000
\widowpenalty=10000
\clubpenalty=10000

% Chapter Style
\usepackage{titlesec}
\titlespacing{\chapter}{0pt}{0pt}{20pt}
\titleformat{\chapter}[hang] 
{\normalfont\huge\bfseries}{\thechapter.}{1em}{} 

% Bibliography Style
\bibliography{library}
\renewcommand\mkbibnamefamily[1]{\textsc{#1}}
\DeclareNameAlias{sortname}{family-given}
\DeclareNameAlias{default}{family-given}
\DefineBibliographyStrings{ngerman}{
    bibliography={Literaturverzeichnis}
}



\usepackage{filecontents}

\begin{filecontents*}{\jobname.bib}
  @book{Knu86,
    author = {Knuth, Donald E.},
    year = {1986},
    title = {The \TeX book},
  }
\end{filecontents*}

\bibliography{\jobname}



\begin{document}

\chapter{Introduction}

\noindent Some text\footcite[p. 38]{Knu86} ....
\newpage


\chapter{Second}

\noindent Some other text \footcite[p. 39]{Knu86}

\end{document}

I am using \footcite[p. x]{author2018} to create source references. Say I am on page 7 and the last citation on this page is Book B from Author A. On page 8, biblatex writes "ibid" in the footnote instead of writing the source again. But when compile the same .tex document on another computer, which uses biblatex 3.3 everything works just fine. I am guessing it's because of the biblatex version but who knows.

So I would like to fix this behavior, so that "ibid" won't be used on the following page.

Answer 1

If you use context-dependent features like pagetracker (to make sure that "ibid" does not appear as first citation on a page), the document must usually be compiled with

1. LaTeX
2. Biber/BibTeX
3. LaTeX
4. LaTeX

i.e. there must be two LaTeX runs after the Biber/BibTeX run. In very rare situations another LaTeX or even Biber/BibTeX run may be required.

You should be warned about required additional runs in the log file with a message along the lines of

Package biblatex Warning: Please rerun LaTeX.
(biblatex)                Page breaks have changed.

_{The message should probably say "may have changed"...}

or

Package biblatex Warning: Please (re)run Biber on the file:
(biblatex)                <file name>
(biblatex)                and rerun LaTeX afterwards.

The phenomenon can be reproduced in

\documentclass[12pt]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
\usepackage{csquotes}
\usepackage[style=verbose-ibid, backend=biber]{biblatex}
\addbibresource{biblatex-examples.bib}

\begin{document}
Lorem\footcite[380]{sigfridsson}
\clearpage
Ipsum\footcite[381]{sigfridsson}
\end{document}

On the first LaTeX run after the Biber run, the citation on page two reads "Ebd." ("ibid."), but on the second run it shows a short citation instead as expected.

The two additional LaTeX runs are necessary because biblatex's pagetracker is implemented much in the same way \label/\ref is in standard LaTeX. On a first run the page information is written to the .aux file and on the second run that information is available from the beginning of the document compilation by reading the .aux file. See Understanding how references and labels work for a great explanation how \label and \ref work (especially section 4 is interesting, because pagetracker needs to get the page numbers right, https://texfaq.org/FAQ-wrongpn, Where does \thepage kick in? and On the basics of writing to & reading from auxiliary files (.aux, .toc, etc.) explain why it is a good idea to implement a page tracker in a way similar to \label).

Avoid infinite compiler passes with biblatex ibid citation styles? has an example where "ibid" and the pagetracker cause an infinite loop of rerun requests.
