Bibliography & Citations

How to Add Citations in LaTeX

LaTeX with BibTeX provides powerful citation management. Store references in a .bib file and cite them automatically.

Create a .bib File

Store references in references.bib:

% references.bib
@article{smith2020deep,
  author  = {Smith, John and Doe, Jane},
  title   = {Deep Learning for NLP},
  journal = {Nature},
  year    = {2020},
  volume  = {42},
  pages   = {123--145}
}

@book{knuth1984texbook,
  author    = {Knuth, Donald E.},
  title     = {The TeXbook},
  publisher = {Addison-Wesley},
  year      = {1984}
}

Cite in Your Document

Use \cite{key} to add citations:

Deep learning has revolutionized NLP~\cite{smith2020deep}.

As noted by Knuth~\cite{knuth1984texbook}, typography matters.

Multiple citations: \cite{smith2020deep, knuth1984texbook}

Add Bibliography

Include the bibliography at the end:

\bibliographystyle{plain}  % or ieee, apa, etc.
\bibliography{references}  % references.bib file

Compile Sequence

Run these commands in order:

pdflatex document.tex
bibtex document
pdflatex document.tex
pdflatex document.tex

💡 Tips

•Google Scholar provides BibTeX entries—click 'Cite' then 'BibTeX'
•Use citekey format: author + year + keyword (smith2020deep)
•\citet{} for textual: 'Smith (2020) showed...' (needs natbib)
