BibTeX

BibTex is a bibliographical management system used in combination with LaTeX, a popular markup language for the composition of academic-level scientific and technical documents. Developed in the 1980s by Oren Patashnik and Leslie Lamport simplify the process of the citation and creation of bibliographies, it enables the management of bibliographical references in an organized and automated way, facilitating the creation of correctly formatted bibliographies in your LaTeX documents

Furthermore, BibTeX can be integrated with citation management tools such as Zotero, Mendeley, or collaborative writing platforms like Overleaf, as shown below.

 

Main Features of BibTeX

 

Management of bibliographical references

  • Files in .bib format: in BibTeX, bibliographical references are memorized in a separate file with .bib extension  . This file contains all the information needed to cite sources such as books, journal articles, book chapters, theses, conference proceedings, and so forth.
  • Standardized formatting: the items in the .bib file follow a standardized format which includes fields such as author, title, year of publication, editor and so on. Each item is identified by a univocal label, which is utilized to retrieve the reference within the LaTeX document. 
     

Integration with LaTeX

  • Automatic citation: within a LaTeX document, the citations are inserted using the reference label present in the .bib file. For example, a citation may appear as \\cite{label}, where "label" is the univocal identifier of the bibliographic item in the .bib file.
  • Automatic generation of the final bibliography: BibTeX manages the creation of the final bibliography automatically, formatting it in accordance with the specified style. This significantly reduces the time and effort needed to create an accurate and well formatted bibliography. 
     

Management of citation styles

  • Predefined styles: BibTeX supports a wide range of citation styles, including the American Psychological Association (APA), Modern Language Association (MLA), Chicago Style, IEEE, and many others. The citation style can be changed by simply modifying a command in the LaTeX document.
  • Custom styles: advanced users can create personalized citation styles to fulfill specific needs, such as those requested by your lecturer or by scientific journals to which you submit your article. 
     

Automatic updates and Compatibility with other bibliographical management tools

  • Automatic updates: when you modify an item in the .bib, all citations within the LaTeX document are automatically updated to show the changes. This feature is particularly  useful in large-size documents, where manual citation management would not be practical.
  • Import from bibliographical databases: BibTeX can import bibliographical references from databases such as PubMed or from academic search engines like Google Scholar, as well as from other sources, further simplifying the citation collecting process.
     

BibTeX in the writing process

  • Creation of the .bib file: first, create the .bib file containing all the necessary bibliographical references; each reference is defined with specific fields and a univocal label.
  • Writing the LaTeX document: during the writing of the document in LaTeX, the citations are inserted using the bibliographical reference label, and the command \\bibliography{filename}  is added at the end of the document to generate the bibliography.
  • Compilation of the document: on termination of the LaTeX document, BibTeX collects the information from the citations and automatically generates the bibliography formatted according to the specified style.


 

Integration of BibTeX with Zotero

  • BibTeX export: Zotero enables the exportation of individual bibliographical references or entire collections in a .bib file that you can utilise directly in your LaTeX document to generate citations and bibliographies. To export bibliographical data, select the collection or the individual references in Zotero, right click and choose the “Export” option and select BibTeX as the export format.
  • Zotero/BibTeX synchronization: Zotero can keep a .bib file synchronized automatically with the Zotero library thanks to plug-ins such as "Better BibTeX"; in this way each modification made to the bibliographical references in Zotero will be immediately reflected in the .bib file, keeping the LaTeX document updated.
  • Insertion of citations: once the .bib file has been exported from Zotero, you can use it in the LaTeX document via the command \bibliography{filename} and insert citations in the text with the command \\cite{label}, where "label" is the identifier of the exported reference.

 

Integration of BibTeX with Overleaf

  • Uploading the .bib file: you can upload directly in Overleaf a .bib file containing all the bibliographic references needed. Overleaf supports manual upload of .bib files but also enables synchronization with external reference management tools such as Zotero and Mendeley.
  • Citation management: after uploading the .bib file, you can insert the citations in the LaTeX document, again using the command \\cite{label}; in this way the bibliography is generated on the basis of the .bib file. Overleaf also offers automatic suggestions for citations when you begin to type \\cite{, facilitating the insertion of the bibliographical references.
  • Automatic updates: if the .bib file is updated, Overleaf regenerates the bibliography automatically during the data entry, ensuring that all the citations are correctly formatted and updated.

 

Integration of BibTeX with Mendeley

  • BibTeX export: as with Zotero, Mendeley allows the export of collections or entire libraries to a .bib: file. You can select the desired bibliographic references, click on “File,” and choose “Export,” selecting BibTeX as the output format. Mendeley can also be configured to keep a .bib file automatically updated, facilitating ongoing use with LaTeX.
  • Use in LaTeX documents: after exporting the .bib file, it can be imported into your LaTeX document and used to insert citations and generate a bibliography through the \\cite{label} and \\bibliography{filename}.
  • Integration with Overleaf: Mendeley can be used in conjunction with Overleaf for reference management. The .bib file exported from Mendeley can be uploaded directly to Overleaf. Mendeley also offers plug-ins and synchronization features that streamline its use within the Overleaf environment.
