14 Reference management


@slide(layout=content-only)

@title
What do we need?

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


@slide(layout=wide-content)

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

@content
*	collection of references in BibTeX 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
    year={1990},                                 % follows
    publisher={Springer}                         % …
}
```

@title
How is it used?

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

* ++ Citing a source: `\cite{<source>}`
* ++ Citing a page: `\cite[p. 15]{<source>}`
* ++ Citing with additional text:<br/>`\cite[<prefix>][<suffix>]{<source>}`
* ++ Referencing the `.bib` file: `\bibliography{<.bib file>}`
* ++ Choosing a citation style: <br/>`\bibliographystyle{<citation style>}`

>	Two things are infinite: the universe and&nbsp;the&nbsp;assortment of citation styles.<cite>Unknown</cite>

Creating and inserting references

@content
*	Use Google Scholar 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 (2012): Der $\LaTeX$-Begleiter.
*	Compare the entries with the results that dblp.org finds for the same titles.
*   Create a new BibTeX file called `literature.bib` in the `exercises/literature` folder.
*   Add the BibTeX entries to the BibTeX file. For this, select your preferred source among Google Scholar and dblp.
*   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.
