Always include the publisher and place of publication (ie town or city). It is usually unnecessary to include a state or country, unless there is potential for confusion between cities with the same name:
… Publisher, Bendigo.
… Publisher, Cleveland, Queensland.
… Publisher, Cleveland, Ohio.
… Publisher, Melbourne.
… Publisher, Rome.
… Publisher, New York.
… Publisher, Boca Raton.
For an international audience, it might be appropriate to include the country. Omit the that precedes the names of some countries in running text:
… Publisher, United Kingdom not … Publisher, the United Kingdom
… Publisher, Netherlands not … Publisher, the Netherlands
An exception is the city The Hague – retain The with a capital T.
Some publications – often those published by international organisations with offices in several countries – do not include a place of publication. For these, either include the location of the head office of the publisher, or omit the place of publication:
Plan International (2011). Because I am a girl: the state of the world’s girls 2011. So, what about boys? Plan International.
It is not usually necessary to include the total number of pages in a book in the reference list. Particular pages for the reference may be listed, if required.
