CZ:Citation style

(This is a preliminary draft which needs to be expanded with information about Humanities citations.)

A citation allows the reader to verify a statement made in the text, see the source of data, gain more detail about a claim, or to explore the original context of a quoted passage. Usually, the text is marked with a superscript hyperlink that is linked to a note, like this, that directs the reader to a reliable source that validates the statement, such as a published book, a scholarly journal, or a government agency website. The citation mark is usually placed after the section to which the citation is most relevant, or at the end of the paragraph, where more than one source of validation may be indicated. It should be placed after any punctuation mark and there should be no space before it.

The advantage of this last method is that it minimizes the number of superscripted numbers appearing in the text. The markup code used to produce the note [1] is this:

<ref name=Example1>A definitive direction to the source of the information is supplied here.</ref>

If a citation is used several times in the one article it is useful to give the citation a name. This is done the first time a source is used by using the markup <ref name=Dickens1859>.

The named reference markup for the note [3] is easy to repeat here using its name.

Listing an article's 'references cited' and 'author written text notes' for the reader to see at the end of the article

The <references/> markup symbol produces the following result when placed just here:

The <references/> markup produces a list of all notes used in the text. See how note [3] has two symbols which are superscripted links referring back to where [3] was used in the text. Try clicking on them to see the service they provide to the reader. Note too how the references are organized in numerical order automatically by the <references/> markup.

Placing the citation list

Generally, the collected citation list is placed directly after the main article and before a bibliography.

Content of the citation

Here is a full citation of an article in a scientific journal that provides comprehensive and definitive information about the source of the article:

Benner SA, Ellington AD, Tauer A. (1989) Modern metabolism as a palimpsest of the RNA world. Proceedings of the National Academy of Science of the U S A. Volume 86, pages 7054-8 doi:10.1073/pnas.86.18.7054 PMID 2476811

This conveys maximum information to the reader, but when many references are cited, takes up much space. It is therefore usual to abbreviate the citation, and most journal citations on Citizendium should follow the following form (very similar to the internet publication Public Library of Science Biology (PLoS Biology):

Benner SA et al. (1989) Modern metabolism as a palimpsest of the RNA world Proc Natl Acad Sci U S A 86:7054-8 PMID 2476811

Note that et al. stands for the Latin et alia, meaning 'and others'.

When providing a doi (digital object identifier) for an article (e.g., the Brenner article above), format it as

[http://dx.doi.org/10.1073/pnas.86.18.7054 Article title.]

This produces a direct link to the article via the article title. For example:

Modern metabolism as a palimpsest of the RNA world.

The link takes you to the journal, showing usually the article's abstract, and links to full-text and downloadable PDF, sometimes free, other times requiring an institutional or personal subscription.

Book citations

A good example is Richard Dawkins (2004) The Ancestor's Tale ISBN 0618005838; Audio (2005) ISBN 0752873210 Reviews here

or alternatively, Dawkins R (2004) The Ancestor's Tale ISBN 0618005838

In many instances it will be necessary to mention the title of a book, or journal in the text of an article, and for this the name, such as A Tale of Two Cities , or Scientific American should be in italics. The markup for this is :

''A Tale of Two Cities''

Abbreviations and their meaning

Journal abbreviations

Again there are several different conventions for abbreviating Journal titles (and a few journals prefer to give journal titles in full). The most common convention used in scientific journals is that used by Index Medicus (and followed by PubMed). Abbreviations are not arbitrary, but follow complex rules; for instance "-ogy" is always lost, so Biology becomes Biol); one exception to this rule is that where the title of a journal is a single word this is never abbreviated. Thus The Journal of Endocrinology is abbreviated as J Endocrinol, but Endocrinology is left unabbreviated.

The National Center for Biotechnology Information (NCBI) provides a service for looking up journal names and abbreviations, and a list of journal names.

Electronic publications and hyper-linked citation resources

It is encouraged that the Citizens' Compendium include hyper-links to readily available publications available through the www. Note that some resources, such as JSTOR, Project Muse, New York Times, and other electronic archives are readily available to researchers who have access to them through their institutional affiliations. For the general public however, access is limited. JSTOR for instance recommends that independent researchers (1) join a participating publisher or scholarly society, (2) visit a subscribing library, or (3) purchase the article from the publisher.[1]

It is recommended that when you hyper-link a citation resource that you include a short notation such as online source.

Practice at Citizendium

The principles behind the choice of any style of citations to provide the reader with enough information to find the source for himself or herself, with efficient use of limited space and an aesthetically pleasing appearance on the page. Although Citizendium is an electronic encyclopedia, there are nevertheless limitations on space to enable articles to be printed compactly. Electronic links mean that, strictly, fewer details need be given to enable sources to be located efficiently - for a citation on PubMed everything is redundant except the PMID number. However citations do more than merely point to a source, they are also open acknowledgments of the origin of ideas and information. Listing sources clearly is an explicit and courteous recognition of the debt that authors have to other authors.
