Considered the best^{[citation needed]} kind of referencing, this system has both shortened 'References' and full details in a 'Bibliography' section. It works best when there are several references to the same book, using different page numbers.

The first time that you reference a certain page or pages from a book, you put something like this after the fact;

<ref name="Bergreen25">{{Harvnb|Bergreen|2007|p=25}}</ref>

You have a 'normal' references section, after the body text, and this entry appears there;

== References ==
{{reflist}}

If/when you use the same book and the same page again (in the body of the article), you just put the short form;

<ref name="Bergreen25"/>

(This is the same principle as 'named references)

To reference a different page in the same book, you would put - for example;

<ref name="Bergreen42">{{Harvnb|Bergreen|2007|p=42}}</ref>

Then, immediately following the references section, you have a section called "Bibliography", which has the full details of the book, like this;

== Bibliography ==
*{{citation|last=Bergreen|first=Laurence|authorlink=Laurence Bergreen|
title=Marco Polo: From Venice to Xanadu|year=2007|publisher=Quercus
|location=[[London]]|isbn=9781847243454}}

Note that the last name of the author and the year in the {{Harvnb}} must match the bibliographic entry, otherwise the link will not work.

The short-form in the references will appear in the form, "^ Bergreen 2007, p. 25", and clicking on it shows (and highlight) the associated bibliographic entry.

It may seem a little complex, but this is the 'recommended way' to do really good referencing - and is used on a great many featured articles.
