Reference management


@slide(layout=content-only)

@title
What do we need?

@content
*	a **bibliography file** (hereafter `.bib` file) for storing references
*	**BibLaTeX** as an interface between the references and LaTeX


@slide(layout=wide-content)

@title
What is this mysterious `.bib` file?

@content
*	collection of references in BibLaTeX format
*	example:

``` {.hljs .lang-tex}
@article{turing1990, % the type of the document and an identifier for the \cite command
    title={The chemical basis of morphogenesis}, % information
    author={Turing, Alan Mathison},              % about
    journal={Bulletin of mathematical biology},  % the
    volume={52},                                 % literature
    pages={153--197},                            % work
    date={1990},                                 % follows

BibLaTeX

@content
* Package for creating and designing bibliographies
* Use of **biber** as backend

<div class="box warning">
**Some well-meaning advice**

You want the references to look professional?

Trust BibLaTeX’s default citation styles!

This conversely means: Avoid fiddling around with styles manually.

@title
What you need

@content

* Include the `BibLaTeX` package in the preamble:

``` {.lang-tex .hljs}
\usepackage[style=<citation-style>, 
backend=biber]{biblatex}
```

* Include the `.bib`-file in the preamble:

``` {.lang-tex .hljs}
\addbibresource{<bib-file>}
```

* Generate the bibliography:

``` {.lang-tex .hljs}
\printbibliography
```

* `BibLaTeX` documentation: [Link](https://ctan.org/pkg/biblatex?lang=de)
* `BibLaTeX` cheat sheet: [Link](https://tug.ctan.org/info/biblatex-cheatsheet/biblatex-cheatsheet.pdf)

@title
Editing the citation style

@content
* Built-in styles for direct use (z.B. `authoryear`, `numeric`, `alphabetic`)
* additionally options for configurations and other styles (z.B. `apa`, `ieee`, `chicago-authordate`)

``` {.lang-tex .hljs}
\usepackage[style=numeric, citestyle=ieee, 
backend=biber]{biblatex}
```
* Change the sorting:

``` {.lang-tex .hljs}
\usepackage[style=numeric, citestyle=ieee, 
sorting=nty, backend=biber]{biblatex}
```

@title
How is it used?

@content
BibLaTeX adds some citation commands to LaTeX. In addition, we need the `natbib` package.

* ++ Citing an author in parentheses: `\parencite{<source>}`
* ++ Citing an author in text: `\textcite{<source>}`
* ++ Citing a page: `\cite[p. 15]{<source>}`
* ++ Citing with additional text:<br/>`\cite[<prefix>][<suffix>]{<source>}`

<table>
  <tr>
	<th>Code</th>
	<th>Description</th>
  </tr>
  <tr>
	<td>`\parencite{turing1990}`</td>
	<td>[Turing, 1990]</td>
  </tr>
  <tr>
	<td>`\textcite{turing1990}`</td>
	<td>Turing (1990)</td>
  </tr>
  <tr>
	<td>`\textcite[p. 159]`<br />`{turing1990}`</td>
	<td>Turing (1990, p. 159)</td>
  </tr>
</table>

An example

@content
``` {.lang-tex .hljs}
\usepackage[style=authoryear, 
maxnames=3, 
minnames=1, 
nohashothers=true, 
dashed=false, 
url=false, 
backend=biber]{biblatex}
```
An exemplary reference in the citation style above:
``` {.lang-tex .hljs}
\textcite{thatcher2002} or in parentheses
\parencite{thatcher2002}.

\printbibliography
```

@title

Creating and inserting references

@content
*   Create a new BibTeX file called `literature.bib` in the `exercises/literature` folder.
*	Use Google Scholar or dblp.org to retrieve BibTeX references for the following $\LaTeX$ handbooks:
	*	Dilip Datta (2017): $\LaTeX$ in 24 Hours. A Practical Guide for Scientific Writing.
	*	Frank Mittelbach / Michel Goossens (2010): Der $\LaTeX$-Begleiter.
*   Add the BibTeX entries to the BibTeX file.
*   Assign unique and meaningful BibTeX keys.
*   Include the BibTeX file in a suitable location, where later on the references should be listed.
*   Cite the two handbooks in the file `exercises/literature/literature.tex`.
*   Make use of the `plain` bibliography style.

@title
The University Library recommends …

@content
* reference management software (esp. **[Zotero](https://www.zotero.org/)**) help to build a literature database, store quotations, and organize one's own notes
* ++ support available from the **library's own reference management team**: literaturverwaltung.ub@uni-bamberg.de
* ++ in Zotero: activate the plugin **["Better BibTeX"](https://retorque.re/zotero-better-bibtex/)** (applies also if you are using `biblatex`)


@slide(layout=extra-content-only)

@title
Setup for Zotero with Better BibTeX

@content
* install **["Better BibTeX"](https://retorque.re/zotero-better-bibtex/)** 
* open Zotero > Tools > Plugins > enable `Better BibTeX for Zotero`
* **TexStudio**: Bibliography > set type to `BibLaTeX`
* **TexStudio**: Options > configure TexStudio > Generate > set standard for bibliography to `Biber`
* **Zotero**: export your library from Zotero, set `Better BibLaTex` as format, and set `keep updated` to true
* **Zotero \& TexStudio**: save the library in your LaTeX project archive and use it as the `.bib`-file

<div class="box warning">
**💡 Further information**

There are plenty of resources about the setup available online.
