.bib File Extension

Developer: Oren Patashnik
File type: BibTex Bibliography database
You're here because you have a file that has a file extension ending in .bib. Files with the file extension .bib can only be launched by certain applications. It's possible that .bib files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .bib file?

A BIB file is a document enlisting reference list, which is formatted with the use of BibTex formatting and often used with the preparation of LaTex documents. BibTex was created in 1985 and is primarily written in WEB/Pascal. The last version that was released was in the year 1988 and the latest was in the year 2010, which constitute a 22-year inactive state. During this absence, several changes were published, namely the reimplementation of bibTex to BibTeXU which support the UTF-8 set of characters, reimplementation of bibTex to bibtex8 that supports 8-bit character set, complete reimplementation from bibTex to CL-BibTeX in Common Lisp, which allows bibtex.bst files directly and capable of converting it to human-readable Lisp.lbst file, bibTex to MLBibTex, which focuses on multilingual features. The platform used for this application is cross-platform. The format typically used is based according to style file and generating LaTex Formatting commands.

how to open a .bib file?

Launch a .bib file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .bib file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .bib files aren't yet associated with it. In this case, when you try to open a .bib file, you can tell Windows which application is the correct one for that file. From then on, opening a  .bib file will open the correct application.

applications that open a .bib file



Used mainly for formatting lists of references, BibTeX is a reference management software that cites sources in a consistent manner by separating the presentation of the bibliographic information from the bibliographic information itself. It is used together with the LaTeX document preparation system, but in using a third-party tool, BibTeX bibliographies can be included in Word Documents. This software uses a plain-text file format that can be created and altered with the use of an arbitrary text-editor. BibTex files has four different type of entries, the @STRING which defines abbreviations, @COMMENT used for comments that BibTex did not take in regard, @PREAMBLE, defines how the formatting of special text should be, and the Entries in which each single reference declares the type of publication. A BibTex entry contains a citation key, type or the word that comes after @ and a number of tags which describes the several characteristics of a specific BibTex entry. Tags may contain the author, year, title and many others, it may be required on some typed on BibTeX entries and some are optional. For templates, the online BibTeX Converter allows the user to choose from a set of templates which are pre-defined.


ProTeXt was developed by Thomas Feuerstack that works with Windows operating system. This is available in four languages namely: German, Italian, French and English. The file size of the downloadable file is 750 MB. There are third party applications included in this downloadable file in CTAN website and those are MiKTeX, ConTeXt, Ghostscript and TeXnicCenter (now known as TeXstudio). Although, the use of TeXnicCenter is highly discourage by some users. These are some latex editors that can be combined together. In order to utilize ConTeXt in ProTeXt and MiKTeX the users must install a Perl (ActivePerl and Ruby) in the users’ operating system. LaTeX involves TeX and translation of XML and DocBook to PDF files. Thru understanding more about LaTeX, users can productively use ProTeXt. This is a freeware IDE (integrated development Environment) application that focuses in Latex creation and alteration. The latest version of ProText is 3.1 released last July 2012.


MiKTeX is a typesetting structure for Microsoft Windows that is created by Christian Schenk. It consists of an execution of TeX and a set of related programs, and gives the tools needed to prepare documents using the TeX/LaTeX markup language, as well a simple tex editor, named TeXworks. It features easy installation, having a complete set of additions (programs, styles, fonts…) are available to help users typeset their documents, it has an integrated package manager installs missing components from the Internet, if required; having an Update Wizard helps users to keep its system up-to-date by installing the latest package updates, it has a fast previewer, having well maintained package repository and it is an open source, meaning that users are welcome to redistribute MiKTeX under certain conditions. The name derives from Christian Schenk's log-in, “MiK for Micro-Kid”. It can update itself by downloading new versions of earlier installed components and packages, and it has an easy installation process. Furthermore, it gives the users the option whether they wish to download any packages that have not yet been installed but are demanded by the current document. Present version of MiKTeX is 2.9 and is available at the MiKTeX homepage. Since version 2.7, MiKTeX has maintained for XeTeX, MetaPost and pdfTeX and compatibility with Windows 7; and is presently being ported to GNU/Linux, with a beta version being available for testing.

a word of warning

Be careful not to rename the extension on .bib files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .bib. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
