===Titles and chapters===
 
* '''title''': The title of the cited source. Titles are displayed in italics, except for short works such as a {{txl|cite press release}} and cited articles in {{tlx|cite news}}, {{tlx|cite journal}}, {{tlx|cite magazine}}, {{tlx|cite web}}, {{tlx|cite conference}}, and {{tlx|cite podcast}}, where the title is shown in quotation marks. Use title case unless the cited source covers a scientific, legal or other technical topic and sentence case is the predominant style in journals on that topic. Use either [[MOS:CT|title case]] or sentence case consistently throughout the article. Do not omit a leading "The" from the title. Subtitles are typically separated from titles with ": " though " – " is also used. [[MOS:TM|As with trademarks]], Wikipedia {{em|does not}} attempt to emulate any stylistic flourishes used by the cited source's publisher, such as ALL-CAPS, all-lower-case, {{sm|Small Caps}}, etc.; use either standard title case or sentence case consistently. If the cited source is itself notable and has a Wikipedia article, the title can be wikilinked. Wikilinking the title will make it impossible to use the "url" parameter to link to an external copy of the cited source, so only do this when citing works that do not need to be externally linked. A link to the actual source is preferred to a link to a Wikipedia article about the source.

* '''script-title''': Languages that do not use a Latin-based alphabet, Arabic, Chinese, Cyrillic, Greek, Hebrew, Japanese, Korean, etc., should not be italicized and may also read [[right-to-left]] (RTL).  To include titles in these languages, use '''script-title'''. Titles in '''script-title''' are wrapped in special HTML markup to isolate RTL script from adjacent left-to-right text.  Part of that special markup is a language attribute that browsers can use to assist in the proper display of the script.  Editors must add a prefix to the script that will identify the language.  The prefix is one of the [[Help:Citation_Style_1#&#124;script-&lt;param>&#x3D; language codes|supported language codes]] followed by a colon: {{para|script-title|ar:<bdi>العربية</bdi>}}.  Unrecognized codes are ignored and will display in the rendered citation.

* '''work''': Used by some templates such as {{tl|cite web}} (where it is aliased to '''website'''), {{tl|cite news}} (aliased to '''newspaper'''), {{tl|cite magazine}} (aliased to '''magazine'''), {{tl|cite journal}} (aliased to '''journal'''), and others where the citation is usually to a specific item (given in the "title" parameter) found in a larger work (this "work" parameter), most commonly an article in a website or print periodical, or an episode in a TV series. {{em|Do not confuse this with the "publisher" parameter}}, which is for the publishing company. If the work is notable and has an article in Wikipedia, it should be wiki-linked at first appearance in citations in the article. If the "title" is already linked-to externally, do not externally link to the "work". If the work title as given by the site/publication would be exactly or substantially the same as the name of the publisher, do not use the "publisher" parameter (see below for more detail).

:On websites, in most cases "work" is the name of the website (as usually given in the logo/banner area of the site, and/or appearing in the {{tag|title|o}} of the homepage, which may appear as the page title in your browser tab, depending on browser). Do not append ".com" or the like if the site's actual title does not include it (thus {{para|work|<nowiki>[[Salon (magazine)|Salon]]</nowiki>}}, not <code>Salon.com</code>). If no clear title can be identified, or the title explicitly is the domain name, then use the site's domain name. Do not falsify the work's name by adding descriptive verbiage like "Website of [Publisher]" or "[Publisher]'s Homepage". Capitalize for reading clarity, and omit "www.", e.g. convert "www.veterinaryresourcesuk.com" to "VeterinaryResourcesUK.com".

:Many journals use highly abbreviated titles when citing other journals (e.g. ''J Am Vet Med'' for ''[[Journal of the American Veterinary Medical Association]]'') because specialists in the field the journal covers usually already know what these abbreviations mean. Our readers usually do not, so these abbreviations should always be expanded.

:If the titled item being cited is part of some other larger work, as in a book in a series, a special issue of a periodical, or a sub-site at a domain (e.g., you are citing the law school's section of a university's website system), it is usually better to use the name of that more specific work than just that of the entire larger work. Various citation templates provide separate fields for such information, e.g. {{para|chapter}}{{para|title}}{{para|volume}}{{para|series}} in {{tlx|Cite book}}. If the nature of the work and its relation to the site, book, or other context in which it is found is complicated or confusing, simply explain the situation after the citation template and before the {{xtag|ref|c}} that closes the citation.

* '''publisher''': the name of the organization that actually published the source. The field should not include the corporate designation such as "Ltd" or "Inc.", unless some ambiguity would result or the organization is usually known with that designation even in everyday use (e.g. [[Apple Inc.]], which otherwise might be confused with [[Apple Records]] and other publishers). "Publisher", "Publishing" and "Publications" can be abbreviated "Pubr.", "Pubg." and "Pubs." respectively, but some templates in this series include a period (full-stop) immediately after this parameter, so the period may have to be omitted; check the output if you abbreviate here. They are usually safe to omit, but are usefully included where the publisher's name might be confusing without it. This is most often the case when the publisher's name is something like "Joshua Martin Publications", which without the designation might be mistaken for a co-author/editor. A leading "The" can generally be omitted, again unless confusion might result (e.g., for [[The International Cat Association]], "The" is part of their official acronym, TICA). If the publisher is notable and has an article independent of the "work", the "publisher" parameter can include a wiki-link to that article, but should never externally link to the publisher's website. Whether the publisher needs to be included depends to an extent on the type of work and sometimes on its recognizability. [[WP:Citing sources]], and most off-Wikipedia citation guides, suggest that it should be used for books (even famous ones), but not necessarily other works. The "publisher" parameter should not be included for widely-known mainstream news sources, for major academic journals, or where it would be the same or mostly the same as the work. For example, the "publisher" parameter should be omitted in these examples:

Do not guess at the publisher when this information is not clear. See next entry for co-published works and how to specify multiple publishers and their locations.

Do not guess at the publisher when this information is not clear. See next entry for co-published works and how to specify multiple publishers and their locations.
* '''location''' (alias {{para|publication-place}}): Geographical place of publication ({{em|not}} where you found your copy, nor location of material in the source). This is usually {{var|City, Country}}, or {{var|City, US State}}. The city name by itself can be used for world-recognized cities like New York, London (except in articles about [[London, Ontario|Canadian]] topics), Paris, Tokyo. Simply having a unique name does not mean it is globally recognizable; e.g., many people do not know where [[Mumbai]] is, especially if they are old enough that it was called [[Bombay]] for much of their lives. If in doubt, be more not less specific, since "Toronto, Canada" and "San Francisco, California" do not actually hurt anything. Be more specific when a {{var|City, Country}} would be ambiguous, e.g. {{para|location|Hanley, Staffordshire, UK}}, versus {{para|location|Hanley, Worcestershire, UK}}. Do not use sub-national postal abbreviations ("DE", "Wilts", etc.), per [[MOS:POSTABBR]]. The location parameter should be omitted when it is implied by the name of the work, e.g. ''The Sydney Morning Herald''. The location parameter should be used when the location is part of a common appellation of but not the actual title of a periodical. For example, the newspaper sometimes called the ''New York Daily News'' is actually [[Daily News (New York)|''Daily News'']] and can be entered with {{para|newspaper|Daily News}} {{para|location|New York}}, which yields: ''Daily News''. New York.  A similar example is ''[[The Times]]'' of London (contrast ''[[The New York Times]]''). Per [[WP:SAYWHEREYOUGOTIT]], provide the location of the edition you are using (e.g., if a publisher has operations in both New York and London and you have the London-published edition, use {{para|location|London}}, even if the publisher's corporate HQ is in New York). If your edition specifically gives multiple locations, this can be indicated with, e.g., {{para|location|New York / London}}. This same technique can be used for co-published works, e.g.: {{para|location|Oakbrook Terrace, Illinois / Los Angeles}}{{para|publisher|<nowiki>[[Council of Science Editors]]</nowiki> / <nowiki>[[Loyola Marymount University]]</nowiki> Press}}; just get them in corresponding order in both parameters. The templates do {{em|not}} have separate {{para|location1|!mxt=y}}, {{para|publisher1|!mxt=y}}, etc., parameters.  For historical publications that are still worth citing and still findable (e.g. via book digitizers – see the "via" parameter below), do not confuse the {{em|printer}} (printing press owner-operator) with the {{em|publisher}} (organization or person that sponsored the work); an edition may have a printer's name in larger type than the publisher, but for citation purposes we care about the publisher. If the distinction cannot be determined for certain in a particular case, list both. While some off-site publishers lean toward omitting publishing locations, they can serve more than purely bibliographical purposes on Wikipedia (e.g. an overabundance of material published in one place in an article about another place may reveal an editorial bias).
+
* '''location''' (alias {{para|publication-place}}): Geographical place of publication ({{em|not}} where you found your copy, nor location of material in the source). This is usually {{var|City, Country}}, or {{var|City, US State}}. The city name by itself can be used for world-recognized cities like New York, London (except in articles about [[Wikipedia:London, Ontario|Canadian]] topics), Paris, Tokyo. Simply having a unique name does not mean it is globally recognizable; e.g., many people do not know where [[Wikipedia:Mumbai|Mumbai]] is, especially if they are old enough that it was called [[Wikipedia:Bombay|Bombay]] for much of their lives. If in doubt, be more not less specific, since "Toronto, Canada" and "San Francisco, California" do not actually hurt anything. Be more specific when a {{var|City, Country}} would be ambiguous, e.g. {{para|location|Hanley, Staffordshire, UK}}, versus {{para|location|Hanley, Worcestershire, UK}}. Do not use sub-national postal abbreviations ("DE", "Wilts", etc.), per [[MOS:POSTABBR]]. The location parameter should be omitted when it is implied by the name of the work, e.g. ''The Sydney Morning Herald''. The location parameter should be used when the location is part of a common appellation of but not the actual title of a periodical. For example, the newspaper sometimes called the ''New York Daily News'' is actually [[Wikipedia:Daily News (New York)|''Daily News'']] and can be entered with {{para|newspaper|Daily News}} {{para|location|New York}}, which yields: ''Daily News''. New York.  A similar example is ''[[Wikipedia:The Times|The Times]]'' of London (contrast ''[[Wikipedia:The New York Times|The New York Times]]''). Per [[WP:SAYWHEREYOUGOTIT]], provide the location of the edition you are using (e.g., if a publisher has operations in both New York and London and you have the London-published edition, use {{para|location|London}}, even if the publisher's corporate HQ is in New York). If your edition specifically gives multiple locations, this can be indicated with, e.g., {{para|location|New York / London}}. This same technique can be used for co-published works, e.g.: {{para|location|Oakbrook Terrace, Illinois / Los Angeles}}{{para|publisher|<nowiki>[[Wikipedia:Council of Science Editors|Council of Science Editors]]</nowiki> / <nowiki>[[Wikipedia:Loyola Marymount University|Loyola Marymount University]]</nowiki> Press}}; just get them in corresponding order in both parameters. The templates do {{em|not}} have separate {{para|location1|!mxt=y}}, {{para|publisher1|!mxt=y}}, etc., parameters.  For historical publications that are still worth citing and still findable (e.g. via book digitizers – see the "via" parameter below), do not confuse the {{em|printer}} (printing press owner-operator) with the {{em|publisher}} (organization or person that sponsored the work); an edition may have a printer's name in larger type than the publisher, but for citation purposes we care about the publisher.

<p>For instance the journal ''[[Physical Review]]'', was numbered volumes 1–35 from 1893–1912 (the first series). In 1913–1969, the volume numbering restarted at 1 and went up to 188 (the second series). In 1970, ''Physical Review'' split into different parts, ''Physical Review A'', ''Physical Review B'', ''Physical Review C'', and ''Physical Review D'', where volumes again restarted at 1 (the third series). Since there are two publications identified as ''Physical Review, Volume 1'', there is a need to distinguish which is which by use of {{para|series|First Series}} or {{para|series|Second Series}}. While ''Physical Review A'' is in the third series of the ''Physical Review'' [[media franchise]], it is the first series of the publication known as ''Physical Review A''. Since there is no confusion about what ''Physical Review A, Volume 1'' could be referring to, there is no need to clarify to which numbering series the journal belong.</p>
