BibTeXisreference management software for formatting lists of references. The BibTeX tool is typically used together with the LaTeX document preparation system. Within the typesetting system, its name is styled as .
BibTeX makes it easy to cite sources in a consistent manner, by separating bibliographic information from the presentation of this information, similarly to the separation of content and presentation/style supported by LaTeX itself.
a.bst file (the style file), which specifies the general reference-list style and specifies how to format individual entries, and which is written by a style designer [..] in a special-purpose language [..], and
.bib file(s) constituting a database of all reference-list entries the user might ever hope to use.
BibTeX chooses from the .bib file(s) only those entries specified by the .aux file (that is, those given by LaTeX's \citeor\nocite commands), and creates as output a .bbl file containing these entries together with the formatting commands specified by the .bst file [..]. LaTeX will use the .bbl file, perhaps edited by the user, to produce the reference list.[1]
During Patashnik’s inactivity 1988–2010, several reimplementations were published:
BibTeXu
A reimplementation of bibtex (by Yannis Haralambous and his students) that supports the UTF-8 character set. Taco Hoekwater has criticized it [1].
bibtex8
A reimplementation of bibtex that supports 8-bit character sets.
CL-BibTeX
A completely compatible reimplementation of bibtex in Common Lisp, capable of using bibtex .bst files directly or converting them into human-readable Lisp .lbst files. CL-BibTeX supports Unicode in Unicode Lisp implementations, using any character set that Lisp knows about.
MLBibTeX
A reimplementation of BibTeX focusing on multilingual features, by Jean-Michel Hufflen. [2]
biblatex
A complete reimplementation. "It redesigns the way in which LaTeX interacts with BibTeX at a fairly fundamental level. With biblatex, BibTeX is only used to sort the bibliography and to generate labels. Instead of being implemented in BibTeX's style files, the formatting of the bibliography is entirely controlled by TeX macros."[3]
Biber
A bibliography processing program for biblatex with a superset of BibTeX functionality, including Unicode 6.0 support, locale-sensitive sorting and UTF-8 citekeys. [3]
BibTeX uses a style-independent text-based file format for lists of bibliography items, such as articles, books, and theses. BibTeX bibliography file names usually end in .bib.
Bibliography entries each contain some subset of standard data entries:
address: Publisher's address (usually just the city, but can be the full address for lesser-known publishers)
annote: An annotation for annotated bibliography styles (not typical)
author: The name(s) of the author(s) (in the case of more than one author, separated by and)
booktitle: The title of the book, if only part of it is being cited
chapter: The chapter number
crossref: The key of the cross-referenced entry
edition: The edition of a book, long form (such as "First" or "Second")
editor: The name(s) of the editor(s)
eprint: A specification of an electronic publication, often a preprint or a technical report
howpublished: How it was published, if the publishing method is nonstandard
institution: The institution that was involved in the publishing, but not necessarily the publisher
journal: The journal or magazine the work was published in
key: A hidden field used for specifying or overriding the alphabetical order of entries (when the "author" and "editor" fields are missing). Note that this is very different from the key (mentioned just after this list) that is used to cite or cross-reference the entry.
month: The month of publication (or, if unpublished, the month of creation)
note: Miscellaneous extra information
number: The "(issue) number" of a journal, magazine, or tech-report, if applicable. (Most publications have a "volume", but no "number" field.)
organization: The conference sponsor
pages: Page numbers, separated either by commas or double-hyphens.
type: The field overriding the default type of publication (e.g. "Research Note" for techreport, "{PhD} dissertation" for phdthesis, "Section" for inbook/incollection)
url: The WWW address
volume: The volume of a journal or multi-volume book
year: The year of publication (or, if unpublished, the year of creation)
In addition, each entry contains a key that is used to cite or cross-reference the entry. This key is the first item in a BibTeX entry, and is not part of any field.
Bibliography entries included in a .bib file are split by types. The following types are understood by virtually all BibTeX styles:
article
An article from a journal or magazine.
Required fields: author, title, journal, year
Optional fields: volume, number, pages, month, note, key
book
A book with an explicit publisher.
Required fields: author/editor, title, publisher, year
Optional fields: volume/number, series, address, edition, month, note, key
booklet
A work that is printed and bound, but without a named publisher or sponsoring institution.
Required fields: title
Optional fields: author, howpublished, address, month, year, note, key
conference
The same as inproceedings, included for Scribe compatibility.
inbook
A part of a book, usually untitled. May be a chapter (or section or whatever) and/or a range of pages.
Required fields: author/editor, title, chapter/pages, publisher, year
Optional fields: volume/number, series, type, address, edition, month, note, key
incollection
A part of a book having its own title.
Required fields: author, title, booktitle, publisher, year
Optional fields: editor, volume/number, series, type, chapter, pages, address, edition, month, note, key
inproceedings
An article in a conference proceedings.
Required fields: author, title, booktitle, year
Optional fields: editor, volume/number, series, pages, address, month, organization, publisher, note, key
The proceedings of a conference.
Required fields: title, year
Optional fields: editor, volume/number, series, address, month, publisher, organization, note, key
techreport
A report published by a school or other institution, usually numbered within a series.
Required fields: author, title, institution, year
Optional fields: type, number, address, month, note, key
unpublished
A document having an author and title, but not formally published.
Required fields: author, title, note
Optional fields: month, year, key
BibTeX formats bibliographic items according to a style file, typically by generating TeX or LaTeX formatting commands. However, style files for generating HTML output also exist. BibTeX style files, for which the suffix .bst is common, are written in a simple, stack-based programming language (dubbed "BibTeX Anonymous Forth-Like Language", or "BAFLL", by Drew McDermott) that describes how bibliography items should be formatted. There are some packages which can generate .bst files automatically (like custom-bib or Bib-it).
Most journals or publishers that support LaTeX have a customized bibliographic style file for the convenience of the authors. This ensures that the bibliographic style meets the guidelines of the publisher with minimal effort.
A.bib file might contain the following entry, which describes a mathematical handbook:
@Book{abramowitz+stegun,author= "Milton {Abramowitz} and Irene A. {Stegun}",title= "Handbook of Mathematical Functions with
Formulas, Graphs, and Mathematical Tables",publisher= "Dover",year= 1964,address= "New York",edition = "ninth Dover printing, tenth GPO printing"
}
If a document references this handbook, the bibliographic information may be formatted in different ways depending on which citation style (APA, MLA, Chicago etc.) is employed. The way LaTeX deals with this is by specifying \cite commands and the desired bibliography style in the LaTeX document. If the command \cite{abramowitz+stegun} appears inside a LaTeX document, the bibtex program will include this book in the list of references for the document and generate appropriate LaTeX formatting code. When viewing the formatted LaTeX document, the result might look like this:
Abramowitz, Milton and Irene A. Stegun (1964), Handbook of mathematical functions with formulas, graphs, and mathematical tables. New York: Dover.
Depending on the style file, BibTeX may rearrange authors' last names, change the case of titles, omit fields present in the .bib file, format text in italics, add punctuation, etc. Since the same style file is used for an entire list of references, these are all formatted consistently with minimal effort required from authors or editors.
Last name prefixes such as von, van and der are handled automatically, provided they are in lower case to distinguish them from middle names. Multiple word last names are distinguished from first and middle names by placing the last names first, then a comma, then the first and middle names. Name suffixes such as Jr., Sr., and III are generally handled by using two comma separators as in the following example:
@Book{hicks2001,author= "von Hicks, III, Michael",title= "Design of a Carbon Fiber Composite Grid Structure for the GLAST
Spacecraft Using a Novel Manufacturing Technique",publisher= "Stanford Press",year= 2001,address= "Palo Alto",edition= "1st",isbn = "0-69-697269-4"
}
If the author does not use a comma to separate the name suffix from the last name, then curly brackets {Hicks III} may be used instead.
Multiple authors should be separated with an and, not with commas:
@Book{Torre2008,author= "Joe Torre and Tom Verducci",publisher= "Doubleday",title= "The Yankee Years",year= 2008,isbn = "0385527403"
}
BibTeX allows referring to other publications via the crossref field. In the following example the 'author:06' publication references to 'conference:06'.
@INPROCEEDINGS{author:06,title={Some publication title},author={First Author and Second Author},crossref={conference:06},pages={330—331},
}@PROCEEDINGS{conference:06,editor={First Editor and Second Editor},title={Proceedings of the Xth Conference on XYZ},booktitle={Proceedings of the Xth Conference on XYZ},year={2006},month = oct,
}
The referred entry must stand below the referring one. Remember to add booktitle to the proceedings entry in order to avoid 'empty booktitle' BibTex warning. The LaTeX output of this input might look like:
Author, First and Author, Second (October 2006), Some publication title, in: Proceedings of the Xth Conference on XYZ, pp 330-331.
Having more than one input file, it is recommended to use the command \bibliography only once and insert the various files separated by commas (and no spaces) inside the curly brackets. Example:
Google Books - The bibliographic information for each book is exportable in BibTeX format via the 'Export Citation' feature.
Google Scholar – Google's system for searching scholarly literature provides BibTeX format citations if you enable the option in 'Scholar Preferences'.
