\section{Introduction}

\begin{markdown*}{hybrid=true}
%</driver>
%<*driver|readme>

This package provides a [biblatex] style to format reference lists in the
[Harvard style][bath-harvard] recommended by the University of Bath Library.

## Installation

The files you need are included in the zip archive available from [GitHub].
If you use the zip archive from [CTAN], you will need to run `luatex
biblatex-bath.dtx` to generate them.

You can use this style simply by copying all the `.bbx`, `.cbx`, `.dbx` and
`.lbx` files into your working directory, that is, the directory holding the
main `.tex` file for your document. If you want the style to be available for
all your documents without having to copy the files over each time, you can
install them using the instructions below.

### Managed way

The latest stable release of biblatex-bath has been packaged for TeX Live and
MiKTeX. If you are running TeX Live and have `tlmgr` installed, you can install
the package simply by running `tlmgr install biblatex-bath`. If you are running
MiKTeX, you can install the package by running `mpm --install=biblatex-bath`.
Both `tlmgr` and `mpm` have GUI versions that you might find friendlier.

### Automated way

A makefile is provided which you can use with the Make utility on
UNIX-like systems:

  * Running `make source` generates the derived files
      - `README.md`
      - `bath.bbx`, `bath.cbx`, `bath.dbx`
      - `english-bath.lbx`, `british-bath.lbx`
      - `biblatex-bath.bib`
      - `biblatex-bath.ins`
  * Running `make` generates the above files and also `biblatex-bath.pdf`.
    Ensure you have (at least) the [luatexja], [adobemapping] and [ipaex]
    packages installed first.
  * Running `make inst` installs the files in the user's TeX tree.
    You can undo this with `make uninst`.
  * Running `make install` installs the files in the local TeX tree.
    You can undo this with `make uninstall`.

### Manual way

You do not need to follow the first step if you downloaded the zip archive from
[GitHub]. You do not need to follow the second step if you already have the PDF
documentation.

 1. Run `luatex biblatex-bath.dtx` to generate the source files.

 2. Compile `biblatex-bath.dtx` with [LuaLaTeX] and [Biber] to generate the
    documentation. You will need, among other things, the [luatexja],
    [adobemapping] and [haranoaji] packages installed; this is just
    for the documentation, not for the biblatex style itself.

 3. If you are using TeX Live, find your home TeX tree using the following
    command at the command prompt/terminal:

    ```
    kpsewhich -var-value=TEXMFHOME
    ```

    If you are using MikTeX, consult the MikTeX manual entry for [integrating
    local additions](http://docs.miktex.org/manual/localadditions.html). You
    can use one of the roots (TeX trees) already defined – preferably one of
    the User roots – or set up a new one.

 4. Move the files to your TeX tree as follows:
      - `source/latex/biblatex-bath`:
        `biblatex-bath.dtx`,
        (`biblatex-bath.ins`)
      - `tex/latex/biblatex-bath`:
        `bath.bbx`,
        `bath.cbx`,
        `bath.dbx`,
        `english-bath.lbx`,
        `british-bath.lbx`
      - `doc/latex/biblatex-bath`:
        `biblatex-bath.pdf`,
        `README.md`

 5. You may then have to update your installation's file name database
    before TeX and friends can see the files.

\section{Using the style}

This style has been tested with \textsf{biblatex} versions 3.12 and 3.14.

To use the style, specify it when you load \textsf{biblatex}. To get the sorting
order of your \emph{citations} right, specify the \texttt{ynt} sorting scheme.
To avoid possible inconsistencies (e.g.~in how disambiguation letters are
assigned), force all entries to use the global reference context:

\begin{tcblisting}{listing only}
\usepackage[style=bath,sorting=ynt]{biblatex}
\assignrefcontextentries[]{*}
\end{tcblisting}

Remember also to specify your \texttt{.bib} file in the preamble:

\begin{tcblisting}{listing only}
\addbibresource{file.bib}
\end{tcblisting}

To get the sorting order of your \emph{references} right, create a new reference
context just before you print your bibliography, using the \texttt{nyt} sorting
scheme:

\begin{tcblisting}{listing only}
\newrefcontext[sorting=nyt]
\printbibliography
\end{tcblisting}

If you forget these extra steps, the \texttt{nyt} sorting scheme will be used
throughout.

To make a citation in the text, use the key that corresponds to the entry in your \texttt{.bib} file:

\begin{tcblisting}{}
While collections can be supplemented by other means \autocite{devlin.etal2021ipp},
the absence of an invisible collection amongst historians is noted by
\textcite[556]{stieg1981inh}. It may be, as \textcite{burchard1965hhl} points
out, that they have no assistants or are reluctant to delegate, or it may be
down to economic factors \autocite{adams2009tc1, adams2014tc2, adams2017tc3,
gb.pa2014}\dots
\end{tcblisting}

Please refer to the documentation for \href{http://www.ctan.org/pkg/biblatex}{\textsf{biblatex}}
for the full range of commands available for in-text citations.

It is strongly recommended to use Biber in place of BibTeX to process your
references, as the style relies on Biber functionality to deal with some of the
more exotic types of entry.


\section{Breaking changes between versions}

The following sections list implementation changes that might affect the way
in which you write your bibliography database files.

In addition to the changes listed, when upgrading between major versions,
you should expect some changes in formatting relating to the evolution of the
Harvard (Bath) style itself. Some of the style's internal settings and
structures may also change without warning.

\subsection{Version 2}

\begin{itemize}
\item
  The code for styling legal references has been completely overhauled, so you can
  represent them more semantically in your bibliography file. The examples below
  show the fields you should now use. As far as possible they have been made
  consistent with the \href{http://ctan.org/pkg/oscola}{\textsf{biblatex-oscola}}
  style, a specialist style implementing the \emph{Oxford Standard for the Citation
  of Legal Authorities}, to enable the same entries to be used with both styles.

  For the sake of backwards compatibility, the version 1 semantics still work,
  but should be considered deprecated; support may be withdrawn in future (major)
  versions of this style.

\item
  In version 1, the \texttt{titleaddon} field was printed unadorned, so you had
  to supply your own brackets. This was to allow greater freedom to `hack' entries.

  With version 2, you should not need to resort to such dirty tricks, so the
  style now applies the brackets for you, in common with styles such as
  \href{http://ctan.org/pkg/biblatex-apa}{\textsf{biblatex-apa}}. Again, for the
  sake of backwards compatibility, before it does this it strips off any brackets
  you may have added by hand around your field value.
\end{itemize}

There is now a companion Bib\TeX\ style available (\texttt{bathx} in version 2+
of the \textsf{bath-bst} package) which is compatible with this style in the
sense that it will render the same \texttt{.bib} file the same way, so long as some
adjustments are made that won't affect the \textsf{biblatex} rendering (mainly
concerning the handling of dates).

\subsection{Version 3}

\begin{itemize}
\item
  Journal titles are now coerced to sentence case, so any capital letters you
  want to keep need to be protected with braces.
\item
  Entries of type \texttt{unpublished} are now explicitly marked as unpublished.
\item
  With entry types that usually expect an \texttt{institution} or
  \texttt{organization} instead of a \texttt{publisher}, if you gave a
  \texttt{publisher} in earlier versions the \texttt{institution}\slash
  \texttt{organization} would be ignored. Now they are printed before the
  publication block.
\item
  Some changes to the Harvard (Bath) style cannot be applied automatically
  (e.g.~the update to how standards are referenced), so you may need to update
  your .bib file accordingly.
\end{itemize}

\subsection{Version 5}

\begin{itemize}
\item
  Series names (except those in \texttt{legislation} and \texttt{jurisdiction}
  entries) are now coerced to sentence case, so any capital letters you
  want to keep need to be protected with braces.
\item
  The `[Online]' tag is now also triggered by \texttt{urldate}\slash
  \texttt{urlyear}.
\item
  The style now sets \lstinline{\bibhang} to 0pt instead of
  \lstinline{\parindent} (or 1em).
\end{itemize}

\subsection{Version 6}

\begin{itemize}
\item
  Entry type clarifications such as `Photograph' and `Computer program' are now
  handled differently from translated titles, in particular as regards their
  position relative to the version, and how they interact with the `[Online]'
  tag. As a result, they should now be placed in \texttt{entrysubtype} rather
  than \texttt{titleaddon}.
\item
  All elements of the title block (including \texttt{titleaddon},
  \texttt{version}, and \texttt{entrysubtype}) now move to the head of the
  reference in the absence of an author\slash editor.
\end{itemize}


\section{Examples}

The examples below are shown in three parts.
The first, marked with \faBook, shows an extract from the
\href{https://library.bath.ac.uk/referencing/harvard-bath}{\emph{Referencing guide: Harvard Bath}} or
\href{https://library.bath.ac.uk/images/referencing}{\emph{Referencing images}}.
The second, marked with \faCog, shows the reference as formatted by \textsf{biblatex}.
The last shows how the reference was entered in the \texttt{.bib} file.
The bottom right corner shows the source of the example: `RX' indicates the `Reference examples (A-Z)' section of the Guide; `RL' indicates the `Organise a reference list' section of the Guide; `RI' indicates \emph{Referencing images}.

You may notice that the examples tend to use BibTeX aliases and conventions for
fields (e.g.~\texttt{address}, \texttt{journal}, \texttt{year}) rather than the
native \textsf{biblatex} fields. This is simply to ease transitions to and from
BibTeX, and not a symptom of recalcitrance on the part of the author.

The Harvard (Bath) style treats preprints as grey literature, and so the
\texttt{report} entry type is the best match semantically. Use \texttt{library}
to specify the name of the preprint repository.

In standard \textsf{biblatex}, you would typically use the natural entry type
for the work and provide preprint details using the \texttt{eprinttype},
\texttt{eprintclass} and \texttt{eprint} fields.

\begin{tips}\item
Use the \texttt{library} field to record the name of the archive.
If the image is on display rather than archived,
use \texttt{institution} instead for the museum, gallery or building.
If you also wish to provide the name of the organisation that published the image,
use the \texttt{publisher} field if the location you provide relates to the publisher,
but the \texttt{organization} field if the location relates to the archive.
\item
Put archival locator information (e.g.\@ box or shelf number) in the \texttt{number} field.
Alternatively, you can split the information across the (non-standard)
\texttt{collection} (\enquote{BRBR}) and \texttt{shelfmark} (\enquote{D/877/1}) fields.
\item
Put the clarification of the resource type in \texttt{entrysubtype}.
In most cases, you can use \texttt{titleaddon} instead,
but \texttt{entrysubtype} will correctly suppress \enquote{Online} being shown
while \texttt{titleaddon} will not.

\end{Verbatim}
\end{bibexbox}

\begin{info}\item
Generally speaking, the year should be in square brackets if it is essential to the citation
(unless it is a Scottish case, in which case it is printed bare), and in parentheses if it is
not.
\end{info}
\begin{tips}\item
By default, the style assumes the year is essential if and only if a volume number is
\emph{not} provided; to override this, you can use the \key{year-essential} option:

\begin{tcolorbox}%
  [ colframe = Slate
  , colback = white
  , fontupper = \footnotesize
  ]
\begin{Verbatim}
  options = {year-essential=true},
\end{Verbatim}
\end{tcolorbox}

To use Scottish style for a case, you can either use the \key{scottish-style} option or
the keyword \texttt{sc}:

\begin{tcolorbox}%
  [ colframe = Slate
  , colback = white
  , fontupper = \footnotesize
  ]
\begin{Verbatim}
  options = {scottish-style},
  keywords = {sc},
\end{Verbatim}
\end{tcolorbox}
\end{tips}

\begin{hacks}\item
This should cover most cases, but legal references tend to enforce their own conventions
no matter what the rest of the reference list is doing,
and it is out of scope for this style to cater for every variation.
Therefore if you need a different format (e.g.~for an American case),
you may prefer to format the reference more-or-less by hand:

\begin{tcolorbox}%
  [ colframe = Slate
  , colback = white
  , fontupper = \footnotesize
  ]
\begin{Verbatim}
  title = {Seldon v.~{Clarkson} {Wright} \& {Jakes}},

% \subsubsection{Date options}
%
% For some resources (ISO standards, Acts of Parliament), the date is part of
