Overview
BibTeX is the standard reference management system used within LaTeX, a powerful typesetting language for scientific and technical writing. It automatically formats references and bibliographies, saving time and ensuring consistency across academic documents.
Researchers use BibTeX to manage large numbers of references, link them to LaTeX manuscripts, and easily switch between citation styles such as APA, IEEE, Harvard, or Vancouver.

Why Use BibTeX?
| Benefit | Description |
|---|---|
 Automatic Formatting | BibTeX handles citation styles and numbering automatically. |
 Style Flexibility | Thousands of .bst styles (APA, IEEE, Elsevier, Nature, etc.). |
 LaTeX Integration | Works seamlessly with Overleaf, TeXShop, TeXworks, MikTeX, etc. |
 Scalability | Handles hundreds of citations without slowing down your document. |
 Reusability | A single .bib file can serve multiple papers and projects. |
 Collaboration | Sync with GitHub, Overleaf, or cloud services for multi-author projects. |
How It Works
A typical BibTeX workflow has four main components:
LaTeX Document (.tex) – The main paper you are writing.
Bibliography File (.bib) – A plain-text file containing all your references.
Style File (.bst) – Determines how references are formatted (APA, IEEE, etc.).
BibTeX Compiler – Processes citations and builds your bibliography automatically.
Example Workflow
Step 1: Create your .bib file
@article{smith2023ai,
author = {John Smith and Jane Doe},
title = {AI in Agricultural Science},
journal = {Journal of Applied Research},
year = {2023},
volume = {58},
number = {4},
pages = {255-272},
doi = {10.1016/j.jar.2023.02.005}
}
Step 2: Cite within LaTeX
According to \cite{smith2023ai}, AI is transforming research productivity.
Step 3: Add the bibliography section
\bibliographystyle{plainnat}
\bibliography{references}
Step 4: Compile
Run the following commands:
pdflatex mypaper
bibtex mypaper
pdflatex mypaper
pdflatex mypaper
