\maketitle

\begin{abstract}
\noindent
\texttt{biblatex-abs-annote} is a lightweight \texttt{biblatex}
supplement that renders an \emph{abstract} and a user-supplied
\emph{annotation} beneath each entry in a bibliography. Both are
standard \texttt{biblatex} fields (\texttt{abstract} and
\texttt{annotation}/\texttt{annote})---no custom entry types are
required. The package works on top of any \texttt{biblatex} style by
patching the standard bibliography drivers.
\end{abstract}

\section{Introduction}

An \emph{annotated bibliography} is a bibliography in which each
reference is followed by a short description---typically an abstract,
a critical note, or both. \texttt{biblatex-abs-annote} adds this
capability to \texttt{biblatex} without replacing your chosen citation
style. It reads two optional fields per entry:

\begin{itemize}[nosep]
  \item \texttt{abstract} --- the journal-supplied abstract, often
    already present in Zotero or Mendeley exports.
  \item \texttt{annotation} --- your own note on the source
    (\texttt{annote} is accepted as a synonym).
\end{itemize}

Either field may be omitted; an entry with neither renders as an
ordinary citation.

\section{Installation}

The package is available on CTAN and is included in TeX~Live and
MikTeX. If it is not already installed, you can fetch it with your
distribution's package manager:

\begin{Verbatim}
# TeX Live
tlmgr install biblatex-abs-annote

# MikTeX picks it up on demand at first use.
\end{Verbatim}

\section{Basic usage}

Load \texttt{biblatex} in the usual way, then add
\texttt{biblatex-abs-annote} afterwards:

\begin{Verbatim}
\documentclass{article}
\usepackage[style=authoryear]{biblatex}
\usepackage{biblatex-abs-annote}
\addbibresource{refs.bib}

\begin{document}
\nocite{*}
\printbibliography
\end{document}
\end{Verbatim}

A sample \texttt{.bib} entry:

\begin{Verbatim}
@article{smith2024,
  author     = {Smith, Jane},
  title      = {Rural Election Administration Challenges},
  journal    = {Journal of Elections},
  year       = {2024},
  volume     = {34},
  pages      = {112--138},
  abstract   = {Examines logistics and staffing in rural precincts.},
  annotation = {Key paper for the adaptive informality framework.}
}
\end{Verbatim}

\section{Package options}

Options are passed as key--value pairs when loading the package:

\begin{Verbatim}
\usepackage[abstract=true, annotation=true, labels=true]{biblatex-abs-annote}
\end{Verbatim}

\begin{center}
\begin{tabular}{@{}llp{0.5\textwidth}@{}}
\toprule
\textbf{Option} & \textbf{Default} & \textbf{Effect} \\
\midrule
\texttt{abstract}   & \texttt{true} & Show abstract blocks. \\
\texttt{annotation} & \texttt{true} & Show annotation blocks. \\
\texttt{labels}     & \texttt{true} & Show ``Abstract:'' / ``Annotation:'' headers. \\
\bottomrule
\end{tabular}
\end{center}

\section{Customization}

All visual aspects are controlled by redefinable commands and lengths.
Override them after loading \texttt{biblatex-abs-annote}:

\subsection*{Labels}
\begin{Verbatim}
\renewcommand{\abAnnotateAbstractLabel}{Summary}
\renewcommand{\abAnnotateAnnotationLabel}{Notes}
\end{Verbatim}

\subsection*{Fonts}
\begin{Verbatim}
\renewcommand{\abAnnotateAbstractFont}{\small\itshape}
\renewcommand{\abAnnotateAnnotationFont}{\small}
\renewcommand{\abAnnotateLabelFont}{\small\bfseries}
\end{Verbatim}

\subsection*{Indentation and spacing}
\begin{Verbatim}
\setlength{\abAnnotateAbstractIndent}{1.5em}
\setlength{\abAnnotateAnnotationIndent}{1.5em}
\setlength{\abAnnotateBlockSkip}{0.5ex}
\setlength{\abAnnotateInterSkip}{0.3ex}
\end{Verbatim}

\section{How it works}

\texttt{biblatex} renders each entry type (\texttt{article},
\texttt{book}, etc.) via a corresponding \emph{bibliography driver}.
\texttt{biblatex-abs-annote} uses the \texttt{xpatch} package to
inject two \texttt{biblatex} macros---\texttt{ab-annotate/abstract}
and \texttt{ab-annotate/annotation}---into each driver immediately
before the closing \texttt{finentry} macro. The macros consult the
\texttt{abstract} and \texttt{annotation} fields on the current entry
and emit an indented block if the field is populated.

Because the injection happens at driver level, the surrounding
citation formatting is whatever your chosen \texttt{biblatex} style
produces. \texttt{biblatex-abs-annote} has been tested with
\texttt{authoryear}, \texttt{apa}, \texttt{chicago-authordate}, and
\texttt{numeric} styles; custom styles work as long as they use the
standard driver names.

\section{Compatibility}

\begin{itemize}[nosep]
  \item Requires \texttt{biblatex} with the \texttt{biber} backend
    (not \texttt{bibtex}). \texttt{natbib} is not supported.
  \item Depends on \texttt{xpatch}, \texttt{changepage}, and
    \texttt{kvoptions}---all standard in TeX~Live and MikTeX.
  \item Patches the 16 standard \texttt{biblatex} drivers. If a custom
    style renames drivers, the patch is silently skipped for that
    driver and the entry renders without annotations.
\end{itemize}

\section{Related formats}

\texttt{biblatex-abs-annote} is the \texttt{biblatex} component of
\texttt{ab-annotate}, a cross-format toolchain sharing the same
\texttt{.bib} conventions:

\begin{itemize}[nosep]
  \item A Typst package (\texttt{@preview/ab-annotate}) providing the
    same annotated-bibliography behavior inside Typst documents.
  \item A Quarto extension (\texttt{cwimpy/ab-annotate}) that renders
    annotated bibliographies to PDF, HTML, Word, and Typst from a
    single \texttt{.qmd}.
\end{itemize}
