**Context**

Touching to the end of my project and attacking biblatex (wild beast).

[This answer](https://topanswers.xyz/tex?q=1491) enables to format the (undervalued) abstract field of the .bib in a pretty tcolorbox and include the abstract directly in text.

[This answer](https://tex.stackexchange.com/questions/249336/bibliography-style-with-abstract-and-numbered-references) shows how to incorporate the abstract field in the bibiliography (I was surprised that abstract= true was not possible in the field settings).

[This answer](https://tex.stackexchange.com/questions/199336/biblatex-reference-both-by-chapter-and-at-the-end-of-the-book) shows how to input a bibliography at the end of each chapter and also at the end of the book.

**Question(s)**

Based on MWE below:

**1. Automatically put a bibliography including abstract field at the end of chapter.**

Manually inputing
printbibliography[segment=\therefsegment,heading=subbibliography] at the end of each of my chapXX.tex seems improvable.

**2. Input a full bibliography at the end of the document, WITHOUT abstracts**

Two problems in one, the bibliographies by type (article/book/report) don't show up, and I'd like them to appear without the abstract field.

You can redefine \renewbibmacro*{finentry}{\finentry} before your final bibliography to remove the abstract from the end of the bib entry:


\documentclass{book}

\usepackage[%
refsegment=chapter,% Pour avoir une bib per chap
bibencoding=inputenc,
hyperref=auto,
style=authoryear,
giveninits=true,
citestyle=alphabetic,
sorting=nyt,
sortcites=true,
doi=false,
isbn=false,
url=false,
eprint=false,
autopunct=true,
maxnames=10,%
maxalphanames=3,%
hyperref=true,
abbreviate=false,
backref=true,
backend=biber%
]{biblatex}

\usepackage{hyperref}

\renewbibmacro*{finentry}{\printfield{abstract}\finentry}

\usepackage{xpatch}
\xpretocmd{\chapter}{%
\ifnum\value{chapter}>0
\fi%
}{}{}

\begin{document}

\chapter{First chapter}

\chapter{Second chapter}

\cite{kastenholz}, \cite{itzhaki}.

\chapter*{Bibliographie}

\renewbibmacro*{finentry}{\finentry}

\end{document}
