Extension:HarvardReferences

Referencing systems
There is common scientific standard (Harvard referencing system).  The two most common types of referencing systems used are:
 * author-date systems—such as the Harvard system, APA and MLA
 * numerical systems—such as Chicago or Turabian, Vancouver and Footnote 

This extension for MediaWiki realises an author-date (Harvard system).

This extension is compatible with Extension:Cite/Cite.php - links in both system can be used in same article. Moreover, links in "Harvard" system can be inserted into description of ref-link, and vice versa. For example,

Example of Harvard References
According to scientists, the Sun is pretty big.[Miller 2005] The Moon, however, is not so big.[Smith 1978:121]

Page numbers in references
Optional page numbers can be used after ":" char in link. Some links with one name and different page numbers can refer to one anchor. For example, [Smith 2008:121] [Smith 2008:51] refers to one anchor with same name: [*Smith 2008]

As separator can be used char "|" instead of char ":".

Highlighting
Extension uses JavaScript to highlight references and backlinks, but works (without "yellow" and multiple-backlinks highlighting) also without JavaScript.
