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.
