A number is allocated to a source in the order in which it is cited in the text. If the source is referred to again, the same number is used. Use Arabic numerals (1,2,3,4,5,6,7,8,9). Either square [ ] or curved brackets ( ) can be used as long as it is consistent. Example: ...as one author has put it "the darkest days were still ahead".(1)
Page numbers are not usually included with the citation number. However should you wish to specify the page number of the source the page/s should be included in the following format:
...as one author has put it "the darkest days were still ahead"(1 p23)
Peart (3 p16-18) has argued that...
If you're directly quoting more than 40 words...
Use a blockquote. Block quotes don't need quotation marks, but are indented 1/2" as a visual cue of a citation.
Peart's (3 p16-18) study found the following:
While research studies have established that socioeconomic status influences disease incidence, severity and access to healthcare, there has been relatively less study of the specific manner in which low SES influences receipt of quality care and consequent morbidity and mortality among patients with similar disease characteristics, particularly among those who have gained access to the healthcare system.
The preferred method is to list each reference number separated by a comma, or by a dash for a sequence of consecutive numbers. There should be no spaces between commas or dashes
For example: Peart (1,5,6-8).
