Quotes allow you to mention an opinion of somebody authoritative, as well as use evidence acquired by other authors.
In this case, you have to separate quotes by using ellipses (…).
The same method allows you to get rid of unnecessary parts of your quote. If you don’t know the year of the article or its author, try to find as much information as you can.
Don’t forget about double spacing that must be used throughout the entire paper.
The author’s name and a page number should be written at the end of the quote, after the period, in parentheses.
