LaTeX is a software system for typesetting documents. LaTeX markup describes the content and layout of the document, as opposed to the formatted text found in WYSIWYG word processors like Microsoft Word, LibreOffice Writer and Apple Pages. The writer uses markup tagging conventions to define the general structure of a document, to stylise text throughout a document, and to add citations and cross-references. A TeX distribution such as TeX Live or MiKTeX is used to produce an output file suitable for printing or digital distribution.
BibTeX is reference 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 . The name is a portmanteau of the word bibliography and the name of the TeX typesetting software.
Reference management software, citation management software, or bibliographic management software is software that stores a database of bibliographic records and produces bibliographic citations (references) for those records, needed in scholarly research. Once a record has been stored, it can be used time and again in generating bibliographies, such as lists of references in scholarly books and articles. Modern reference management applications can usually be integrated with word processors so that a reference list in one of the many different bibliographic formats required by publishers and scholarly journals is produced automatically as an article is written, reducing the risk that a cited source is not included in the reference list. They will also have a facility for importing bibliographic records from bibliographic databases.
CiteULike was a web service which allowed users to save and share citations to academic papers. Based on the principle of social bookmarking, the site worked to promote and to develop the sharing of scientific references amongst researchers. In the same way that it is possible to catalog web pages or photographs, scientists could share citation information using CiteULike. Richard Cameron developed CiteULike in November 2004 and in 2006 Oversity Ltd. was established to develop and support CiteULike. In February 2019, CiteULike announced that it would be ceasing operations as of March 30, 2019.
Bibliographic coupling, like co-citation, is a similarity measure that uses citation analysis to establish a similarity relationship between documents. Bibliographic coupling occurs when two works reference a common third work in their bibliographies. It is an indication that a probability exists that the two works treat a related subject matter.
refer is a program for managing bibliographic references, and citing them in troff, nroff, and groff documents. It is implemented as a preprocessor.
EndNote is a commercial reference management software package, used to manage bibliographies and references when writing essays, reports and articles. EndNote was written by Richard Niles, and ownership changed hands several times since it was launched in 1989 by Niles & Associates: in 2000 it was acquired by Institute for Scientific Information’s ResearchSoft Division, part of Thomson Corporation, and in 2016 by Clarivate. EndNote's main competitors are Mendeley and Zotero. Unlike Mendeley and Zotero, EndNote is neither free-to-use nor offers a freemium model.
refbase is web-based institutional repository and reference management software which is often used for self-archiving. refbase is licensed under the GPL and written in PHP and uses a MySQL backend.
RIS is a standardized tag format developed by Research Information Systems, Incorporated to enable citation programs to exchange data. It is supported by a number of reference managers. Many digital libraries, like IEEE Xplore, Scopus, the ACM Portal, Scopemed, ScienceDirect, SpringerLink, Rayyan, Accordance Bible Software, and online library catalogs can export citations in this format. Citation management applications can export and import citations in this format.
Zotero is free and open-source reference management software to manage bibliographic data and related research materials, such as PDF and ePUB files. Features include web browser integration, online syncing, generation of in-text citations, footnotes, and bibliographies, integrated PDF, ePUB and HTML readers with annotation capabilities, and a note editor, as well as integration with the word processors Microsoft Word, LibreOffice Writer, and Google Docs. It was originally created at the Center for History and New Media at George Mason University and, as of 2021, is developed by the non-profit Corporation for Digital Scholarship.
ContextObjects in Spans (COinS) is a method to embed bibliographic metadata in the HTML code of web pages. This allows bibliographic software to publish machine-readable bibliographic items and client reference management software to retrieve bibliographic metadata. The metadata can also be sent to an OpenURL resolver. This allows, for instance, searching for a copy of a book at a specific library.
OttoBib.com was a website with a free tool to generate an alphabetized bibliography of books from a list of International Standard Book Numbers (ISBN) with output in MLA, APA, Chicago/Turabian, BibTeX and Wikipedia {{cite book}} format. Each query also generated a "temporary" permalink which could be used to recall the bibliography without reentering the ISBN data. The site was a metasearch engine, integrating data from several sources, including the U.S. Library of Congress API, the Amazon.com database of books, and ISBNdb.com. OttoBib accepted ISBNs with either 10 or 13 digits.
The following tables compare notable reference management software. The comparison includes older applications that may no longer be supported, as well as actively-maintained software.
BibDesk is an open-source reference management software package for macOS, used to manage bibliographies and references when writing essays and articles. It can also be used to organize and maintain a library of documents in PDF format and other formats. It is primarily a BibTeX front-end for use with LaTeX, but also offers external bibliographic database connectivity for importing, a variety of means for exporting, and capability for linking to local documents and automatically filing local documents. It takes advantage of many macOS features such as AppleScript and Spotlight.
The AMSRefs package is an extension package for LaTeX that facilitates the creation of bibliographies and citations in LaTeX documents. Use of AMSRefs allows for the retention of rich markup that makes references easier to reuse in other publishing environments, such as on the Web, in other book or journal formats, or with citation services. The package is available for free on the American Mathematical Society's website.
RefDB is a client/server reference database and bibliography tool for markup languages like SGML, XML, and LaTeX. It is suitable for standalone use for the purpose of self-archiving, but can be used as an institutional repository as well. Data storage proper is done in one of several supported SQL database engines. RefDB runs on Unix-like operating systems and on Windows/Cygwin. RefDB is licensed under the GPL.
Referencer is a GNOME application to organize documents or references, and ultimately generate a BibTeX bibliography file. It is designed with the scientist/researcher in mind, and "document" may be taken to mean "paper" in general, although Referencer can deal with any kind of document that BibTeX can. Chief among Referencer's capabilities is the automatic acquisition of bibliographic information (metadata) for some kinds of documents. Upon adding a PDF file to a Referencer library file, it will automatically be searched for key identifiers such as a DOI code or arXiv identifier. If either of these is found, Referencer will attempt to retrieve the metadata for the document via the internet. However, metadata fetching for newer additions to arXiv is broken because of the change of format.
Qiqqa is a free and open-source software that allows researchers to work with thousands of PDFs. It combines PDF reference management tools, a citation manager, and a mind map brainstorming tool. It integrates with Microsoft Word XP, 2003, 2007 and 2010 and BibTeX/LaTeX to automatically produce citations and bibliographies in thousands of styles.
MultiMarkdown is a lightweight markup language created by Fletcher T. Penney as an extension of the Markdown format. It supports additional features not available in plain Markdown syntax.
Citavi is a program for reference management and knowledge organization for Microsoft Windows published by Swiss Academic Software in Wädenswil, Switzerland. Citavi is very widely used in Germany, Austria, and Switzerland, with site licenses at most universities, many of which offer training sessions and settings files for Citavi.
