and its complementary closing template  are used to apply any of several optional styles or presentational choices for bibliographies or reference lists—that is, lists of fully-specified references, sources, or works cited, sorted alphabetically by author or contributor—that appear in Wikipedia articles.  These bibliographies or reference lists frequently appear in dedicated sections within an article, variously titled == References ==, == Works cited ==, == Bibliography ==, == Further reading ==, == Published works ==, and so on.  Wikipedia referencing or citation systems that use bibliography-style reference lists include: 'shortened' footnotes and 'general' referencing.Previously they were also used with inline parenthetical referencing. The 'full' footnote referencing system does not use those lists. Any articles may contain a "Further reading" section or other sections with bibliography-style listings, that  formatting could be applied to.  The formatting options provided by this template are: +refbegin template options/parameters Option How to get it Notes default display {{refbegin}}no parameters needed, default fontsize is 90% of standard fontsize display list in multiple columns {{refbegin|30em}}where 30em determines the width of columns based on the browser's screen width. Can be any value generally (e.g. 20em, 50em, etc.). apply hanging indent {{refbegin|indent=yes}}will apply hanging indent if an individual reference wraps over more than one line in the browser's display window Each use of , with or without parameters, needs an accompanying  closing template to 'turn off' the formatting; refend does not need any parameters.  Font size reduction is applied by default. Multi-columns and hanging indent may be applied separately or combined.   ব্যবহার  This template is used only for references—it should not be used to create lists of text which are smaller, in columns, or which have other style data associated with them.To place general content in columns, use Template:Div col.  With all (optional) parameters shown: == References == {{refbegin |30em |indent= }} * list of bibliography/references entries.. ... {{refend}}   Placement  The  is placed immediately below the header of the bibliography/references section its formatting will be applied to. The closing  template is placed within the same section, at the end of the bibliography/references list content.  When used, each occurrence of  should always be paired with a corresponding closing  template: == References == {{refbegin}} * 1st entry in the bibliography/references list.. * 2nd entry in the bibliography/references list.. ... * last entry in the bibliography/references list.. {{refend}}  The formatting provided by  is "turned on" at the location where the template is placed, and is applied to all text after and below it, until it is "turned off" by a closing  template (or </div> tag). Failing to provide a closing  may produce unwanted effects in other sections that may appear below the 'References', 'Bibliography' etc. section, such as 'External links' sections that are usually placed at or near the article's end.   Option 1: Default behaviour  The default usage (without parameters) applies a style that reduces the text size of the bibliographies/reference list entries. This can be useful to make a long bibliography/list of references display more compactly, and it also mimics the formatting style applied to footnotes by the  template.  The  formats footnotes—any text in the article body that is placed between  tags—that are auto-generated by the cite.php extension, called by . In the case of articles using the 'shortened' footnotes referencing system, these footnotes will typically contain an abbreviated citation such as  that corresponds with an entry in the bibliography/references list section (other text such as discursive notes may appear as well).  The font size is set to 90% in the corresponding TemplateStyles page.  If the 'full' footnotes referencing system is used (i.e. there is no separate bibliography/references list, all cites/references are defined in  tags), then use  alone: == References == {{reflist}}  If there is a bibliography/references list but no footnoted citations (e.g. in general references or parenthetical referencing systems) then use  and  like so:  == References == {{refbegin}} * general reference 1 * general reference 2 {{refend}}  If there are footnoted citations and a separate bibliography/references list (i.e., the WP:CITESHORT system), then place  to generate the footnotes in one section (immediately above the bibliography/references list), and use  in the latter section:  == Notes == {{reflist}} <!--this will auto-generate the numbered list of footnotes/cites -->  == References == {{refbegin}} * bibliography entry / reference 1 * bibliography entry / reference 2 * etc {{refend}}   Option 2: Multiple columns  If a value with a unit is supplied as the first parameter, i.e. 30em, the template will display the bibliography/references list in columns with a minimum width of that value, allowing the browser to determine the optimal number of columns.The template previously supported defining the quantity of columns rather than the maximum width of columns. For example, {{refbegin|2}} would have displayed the list in two columns. In 2023, this was deprecated. The template will treat an integer value greater than 1 in the first parameter as 30em, so {{refbegin|2}}, {{refbegin|4}}, and {{refbegin|30em}} all render the same as of October 2023. This is a fallback and may be removed in the future. Using {{refbegin|30em}} for instance is useful for short citations. If no parameter is specified, the default is a single column.  == References == {{refbegin|30em}} * {{cite journal |author= Southworth, Jane |author2= Catherine Tucker |date= August 2001 |title= The Influence of Accessibility, Local Institutions, and Socioeconomic Factors on Forest Cover Change in the Mountains of Western Honduras |url= http://www.bioone.org/doi/pdf/10.1659/0276-4741(2001)021%5B0276:TIOALI%5D2.0.CO%3B2 |format= PDF reproduction, BioOne online |journal= Mountain Research and Development |location= Boulder, CO |publisher= International Mountain Society and United Nations University |volume= 21 |issue= 3 |pages= 276–283 |doi= 10.1659/0276-4741(2001)021[0276:TIOALI]2.0.CO;2  |issn= 0276-4741 |oclc= 107067006}} * {{cite journal |author= Tucker, Catherine M. |author2= Darla K.

This option can be useful in long bibliographies/reference lists and in particular when individual entries in the list are long, i.e. they wrap over more than one line in the browser display window. Applying a hanging indent to the list makes it much easier to distinguish the keywords (i.e. normally the authors' names) in the bibliography and makes them stand out from preceding and succeeding lines of text. Hanging indents in bibliographies also form part of several widely used citation style implementations, such as APA, MLA, and Chicago.  To use, set .
