Understanding BibTeX: A Comprehensive Guide for LaTeX/Overleaf Users

What is BibTeX?

BibTeX is a powerful program for creating style-correct reference lists and citations directly in Overleaf or LaTeX documents, allowing you to seamlessly organize and format your bibliography. BibTeX works with a “bib” file in which all your references are stored, simplifying the citation process in LaTeX.

Common BibTeX Entry Types

BibTeX offers several entry types to cover various sources, including:

  • article: For journal articles.
  • book: For books.
  • inbook: For chapters within a book.
  • inproceedings: For conference papers.
  • misc: For miscellaneous sources that don’t fit other types.
  • phdthesis: For PhD theses.
  • mastersthesis: For Master’s theses.
  • techreport: For technical reports.

Essential BibTeX Fields

Each BibTeX entry type includes fields to store specific information:

  • author: The author(s) of the work.
  • title: The title of the work.
  • year: The year of publication.
  • journal: The journal name (for articles).
  • publisher: The book’s publisher.
  • pages: Page numbers (for articles or book chapters).
  • volume: The volume number (for journal articles).
  • number: The issue number (for journal articles).
  • address: The publisher’s address.
  • edition: The book edition.
  • institution: The institution publishing the report or thesis.

Choosing the Right BibTeX Style

BibTeX uses various styles to format your bibliography:

  • plain: A simple numeric style.
  • unsrt: Similar to plain but entries are in citation order.
  • alpha: Uses alphabetic labels (e.g., Jon90 for an article by Jones from 1990).
  • abbrv: Abbreviates first names, months, and journal names.

Extending BibTeX with Natbib

Natbib is a package that extends BibTeX, offering more citation options. Key commands include:

  • \citet{key}: Textual citation, e.g., “Smith (2020) shows…”
  • \citep{key}: Parenthetical citation, e.g., “(Smith, 2020)“.

Advancing with BibLaTeX

BibLaTeX is a modern alternative to BibTeX, providing more features and better citation style support. Key commands include:

  • \autocite{key}: Automatically selects the citation style based on context.
  • \footcite{key}: Puts the citation in a footnote.

To use BibLaTeX, include it in your document preamble:

\usepackage[backend=biber]{biblatex}
\addbibresource{yourbibfile.bib}

Collaborate with CiteDrive

CiteDrive is a BibTeX generator and an online tool for shared reference management and use of BibTeX-based references. The application integrates seamlessly with Overleaf and other LaTeX editors and allows multiple users to work on the same reference file simultaneously. Key features include real-time updates, collision control, automatic formatting, key generation, tags, list and project organization, online search, converter and easy bibliography sharing.

Example BibTeX Entry

Here is a simple example of a BibTeX entry for ‘An Example Article,’ a paper by John Doe:

@article{key,
author = {John Doe},
title = {An Example Article},
journal = {Journal of Examples},
year = {2023},
volume = {42},
pages = {123-456},
}

Summary

BibTeX is essential for managing references in LaTeX documents, supporting various entry types and fields. Extensions like Natbib and BibLaTeX enhance BibTeX’s functionality, while CiteDrive facilitates collaborative bibliography management.
