What is the BibTeX format?

BibTeX is a specialized reference management tool and file format designed primarily for use with LaTeX documents. It enables the efficient creation and automated formatting of bibliographies. A BibTeX file uses a plain-text structure with a .bib extension, storing bibliographic entries as distinct records. Each entry specifies a type (e.g., `@article`, `@book`) and a unique citation key, followed by comma-separated fields like `author`, `title`, `year`, and `journal`. Processing involves compiling the LaTeX document alongside the .bib file using tools like BibTeX or BibLaTeX to generate a formatted bibliography list matching a specified citation style. Crucially, it separates reference data management from document formatting logic. The format dramatically simplifies managing extensive reference lists in academic writing, ensuring consistency and accuracy. It reduces manual formatting errors and eases adapting citations to different publication styles. Key applications include theses, journal articles, and technical reports. Researchers implement it by creating a .bib database, citing keys within their LaTeX source, and running the necessary compilation sequence to produce the final bibliography. This integration saves significant effort in scholarly publishing workflows.
