Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, words or less. Informative Abstract The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it.
A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author.
The length varies according to discipline, but an informative abstract is usually no more than words in length. In that a highlight abstract cannot stand independent of its associated article, it is not a true abstract and, therefore, rarely used in academic writing.
Writing Style. Use the active voice when possible , but note that much of your abstract may require passive sentence constructions. Regardless, write your abstract using concise, but complete, sentences. Get to the point quickly and always use the past tense because you are reporting on a study that has been completed. Abstracts should be formatted as a single paragraph in a block format and with no paragraph indentations.
In most cases, the abstract page immediately follows the title page. Do not number the page. Rules set forth in writing manual vary but, in general, you should center the word "Abstract" at the top of the page with double spacing between the heading and the abstract. Composing Your Abstract. Although it is the first section of your paper, the abstract should be written last since it will summarize the contents of your entire paper. Ethically, however, the project raises serious questions about the morality of genetic engineering.
To handle both the medical opportunities and ethical dilemmas posed by the genome project, scientists need to develop a clear set of principles for genetic engineering and to continue educating the public about the genome project. The examples above are taken from Form and Style 10th ed. Note: The following are specifications for an abstract in APA style, used in the social sciences, such as psychology or anthropology.
If you are in another discipline, check with your professor about the format for the abstract. Many papers in the social sciences, natural sciences, and engineering sciences follow IMRaD structure: their main sections are entitled Introduction, Methods, Results, and Discussion.
People use the abstract to decide whether to read the rest of the paper, so the abstract for such a paper is important. Because the abstract provides the highlights of the paper, you should draft your abstract after you have written a full draft of the paper. Typically, an abstract for an IMRaD paper or presentation is one or two paragraphs long — words.
Abstracts usually spend. Combining all of the most important aspects of your work into a paragraph of words or less can be a challenging task. However, knowing what to avoid when writing the abstract can make the job a little easier. Once you have completed the abstract, it is important to check that all of the information you have included here agrees with the information in the main body of your paper.
After working on it for so long, it can sometimes be difficult to objectively evaluate whether your abstract is clear, especially because you are likely to be very familiar with the conventions within your discipline. Consider giving your abstract to a colleague working in a separate discipline and ask him or her to read it. Ask your colleague whether the study is clear based solely on the abstract. This can help you to determine which areas of the abstract will require revisions, either to clarify your meaning or to better highlight your major findings.

What follows are some sample abstracts in published papers or articles, all written by faculty at UW-Madison who come from a variety of disciplines. We have annotated these samples to help you see the work that these authors are doing within their abstracts. The social science sample Sample 1 below uses the present tense to describe general facts and interpretations that have been and are currently true, including the prevailing explanation for the social phenomenon under study.
That abstract also uses the present tense to describe the methods, the findings, the arguments, and the implications of the findings from their new research study.
The authors use the past tense to describe previous research. The humanities sample Sample 2 below uses the past tense to describe completed events in the past the texts created in the pulp fiction industry in the s and 80s and uses the present tense to describe what is happening in those texts, to explain the significance or meaning of those texts, and to describe the arguments presented in the article. The science samples Samples 3 and 4 below use the past tense to describe what previous research studies have done and the research the authors have conducted, the methods they have followed, and what they have found.
In their rationale or justification for their research what remains to be done , they use the present tense. Gonalons-Pons, Pilar, and Christine R. Analyzing underground pulp fiction publications in Tanzania, this article makes an argument about the cultural significance of those publications.
