BIBTEX (BibTeX Bibliography Database File)
The BIBTEX Misc file format
Files that are saved as BIBTEX files are considered documents. They contain information that is used by BibTeX, a program that enables and facilitates the citation and incorporation of bibliographies in scientific and academic texts written using LaTeX. The BIBTEX file enables users to search bibliographies and cite them in their work as they contain different references.
