How can I repeat my BibLaTex Bibliography?

Question

I want a document structured as follows:

TOC: Intro Chapter 1 Chapter 2 Outro Bibliography (everything cited until this point) Appendix

Then I want Intro.... all the chapters, the bibliography.

However than I want ANOTHER TOC which is for the Appendix and looks like this:

Appendix TOC List of Appendices A Chapter 2: Same Title as in the main part A.1 Here is a section with some citations
A.2 Included Papers Chapter 3:Another chapter that is the same as in the first part B.1 Some section with new references
Appendix References

The crux is: The appendix has two bibliographies: one that is supposed to only include references until this point (here A.1) and another one that includes all references in the appendix, but not from the current file.

However, so far I have an error: somehow all citations that are below the first appendix bibliography also go into the appendix bibliography.

Maybe it has to do with using Overleaf?

Put differently: My question is how can I have the first appendix bib to be included into the second one, too?

I deep edited the question cause I realised I can do better with a shorter MWE!

The obvious solution is to '''nocite''' everything that is in the first appendix bibliography. Yes, I do that currently, but I do not really like that "workaround".

Edit: I new tried the following in order to get 3 bibliographies (one of sec 1, one of sec 2, and one combining sec 2 and 3 but not sec 1). I am here and I cannot go on to combine the latter 2 bibliographies

\documentclass{article}

\usepackage[style=authoryear-comp]{biblatex}
\addbibresource{references.bib}

\begin{document} 
\tableofcontents
\section{Sec 1}
\begin{refsegment}
  \cite{Ajzen1991}
  \printbibliography[segment=1, title={First bib}, heading=subbibintoc]
\end{refsegment}

\section{Sec 2}
\begin{refsegment}
  \cite{Rogers2003}
\end{refsegment}

  \printbibliography[segment=2, title={First bib}, heading=subbibintoc]


\section{Sec 3}
\begin{refsegment}
  \cite{Liberman2007}
\end{refsegment}
  \printbibliography[segment=3, title={First bib}, heading=subbibintoc]
%HERE I Actually would love to have section 2 and 3 (not all sections)

Answer 1

You can solve your problem by using a mixture of refsection and refsegment which are allowed to be nested. So the basic structure is the following:

\begin{refsegment}
Chapter 1
\end{refsegment}
\printbibliography[segment=1]
\begin{refsection}
\begin{refsegment}
Chapter 2
\end{refsegment}
\printbibliography[segment=2]
Chapter 3
\end{refsection}
\printbibliography[section=1]

Here I've enclosed Chapter 2 and 3 in their own refsection, but Chapter 2 also contains its own refsegment so that it can have an individual bibliography. We can then print the combined references of chapters 2 and 3 using the refsection.

Here's your full document:
