2. The annotation. This section summarizes and analyzes the article. A summary is a shorter version of a larger "whole" and, in general, is no more than 20% of the source text. In an annotation the summary is even shorter.
How to prepare your summary:
To effectively summarize a source, you must read the entire source. Do not try to simply summarize the abstract or paraphrase one or two sentences from the article.
Skim the article once so that you understand the organization and headings. Read a second time more carefully.
Take notes while you read the text. What are the main ideas of each paragraph?
