Abstracts enable an investigator who is seeking information on a subject to determine quickly whether the desired facts are contained in an article or whether the article is of sufficient interest to her to warrant her reading it. Abstracts give to scientists, teachers, and others, who are not especially interested in details, a quick method of keeping themselves informed of the trend of current scientific literature. Abstracts give a brief resume of articles so that the complete article may be read more intelligently. With the main facts in mind, the reader can give more attention to the details in the paper. Abstracts frequently defeat their purpose by being primarily descriptive of the article rather than a statement of its contributions.
Some abstracts are longer than the length, value, and importance their articles justify.
Others are so brief and general as to be unworthy of the name abstract. Accompanying this handout are two articles. One of the articles has the author's abstract included, the second article's abstract has been deleted. Based on the characteristics of an abstract given above, critique the author's abstract. Write a good abstract for the second article.
