Non-governmental organisation publication [from Print source using APA 6th ed.]
The format is very much like a book, with author, year, title, place of publication and publisher. However, if it comes from a recognised series, include the series title and number in round brackets after the title. Some types of report may have a corporate author (the name of the organization responsible for the report goes in the author position).
Author, initials. (year). Title of the report (Series Title and number - if there is one). Place of publication: Publisher.
Child Poverty Action Group. (2005). Ten steps to a society free of child poverty: Child Poverty Action Group's manifesto to eradicate child poverty. London: Child Poverty Action Group.
If there is no identifiable author, begin your reference with the title of the report. Cite the first few words of the title in the text of your work and italicise them.
