Abstract
A summary of the text, or an explanation of what is in it. Should be short (maximum 500 words) and as far as possible, describe what is actually in the text, rather than what you think about it. 'This article is about the theory of money' is an abstract. 'This article is crap' is a review. 'This article summarises Friedman's erroneous views about money' is an abstract if the work is about Friedman, and a review if the work is by Friedman
