Stem Cell Research Paper Abstract Apa

APA (American Psychological Association) documentation is used in scientific research papers. Because Internet technology is constantly changing, so is the APA documentation style for information published on the Net. The purpose of this Web page is to provide you with the most up-to-date information about APA style for documenting electronic sources. (To document other sources, please see our handbooks, or check the Publication Manual of the American Psychological Association.) On this page, you will also find links to the pages of a sample APA research paper.

APA style prefers a reference to the print form of a source, even if it is available on the Net. If you have read only the electronic form of an article’s print version, add “Electronic version” in brackets after the title of the article. If an on-line article has been changed from the print version or has additional information, follow the same general format for the author, date, and title elements of print sources, but follow it with a “retrieved” statement, citing the date of retrieval and the electronic address.

NOTE: Titles and subtitles of articles are not capitalized (except for the first word) or enclosed in quotation marks. (The names of periodicals are capitalized and italicized.)

Periodical, identical to print version

Author, A., & Author, B. (year, month day). Title
of article [Electronic version]. Title of
eriodical, volume number or other designation,
inclusive page numbers.

Periodical, different than print version

Author, A., & Author, B. (year, month day). Title
of article. Title of Periodical, volume number,
inclusive page numbers. Retrieved Month day,
year, from electronic address

Notes: Include an issue number in parentheses following the volume number if each issue of a journal begins with page 1. Use “p.’ or “pp.” before the page numbers of newspaper articles. Page numbers are often not relevant for Internet-only sources. End the citation with a period unless the final element is an electronic address.

Notes: The title of the article is followed by the name of the journal (italicized), the volume number (italicized), and the issue number (in parentheses, not italicized). If applicable, “Article 000’ (or other designation) is placed after a comma that follows the issue number. The entry ends with the “retrieved” statement, omitting end punctuation. When forced by line length to break an Internet address, always break it after a slash mark or before a period, and never insert a hyphen at the break.

Stem Cell Research: An Annotated Bibliography

Holland, Suzanne. The Human Embryonic Stem Cell Debate: Science, Ethics, and Public Policy. Boston: MIT P, 2001.

This is the annotation of the above source, which is formatted according to MLA 2016 (8th ed.) guidelines for the bibliographic information listed above. If one were really writing an annotation for this source, one would offer a brief summary of what this book says about stem cell research.

After a brief summary, it would be appropriate to assess this source and offer some criticisms of it. Does it seem like a reliable and current source? Why? Is the research biased or objective? Are the facts well documented? Who is the author? Is she qualified in this subject? Is this source scholarly, popular, some of both?

The length of your annotation will depend on the assignment or on the purpose of your annotated bibliography. After summarizing and assessing, you can now reflect on this source. How does it fit into your research? Is this a helpful resource? Too scholarly? Not scholarly enough? Too general/specific? Since "stem cell research" is a very broad topic, has this source helped you to narrow your topic?

Senior, K. "Extending the Ethical Boundaries of Stem Cell Research." Trends in Molecular Medicine, vol. 7, 2001, pp. 5-6.

Not all annotations have to be the same length. For example, this source is a very short scholarly article. It may only take a sentence or two to summarize. Even if you are using a book, you should only focus on the sections that relate to your topic.

Not all annotated bibliographies assess and reflect; some merely summarize. That may not be the most helpful for you, but, if this is an assignment, you should always ask your instructor for specific guidelines.

Wallace, Kelly. "Bush Stands Pat on Stem Cell Policy." CNN. 13 Aug. 2001.

Using a variety of sources can help give you a broader picture of what is being said about your topic. You may want to investigate how scholarly sources are treating this topic differently than more popular sources. But again, if your assignment is to only use scholarly sources, then you will probably want to avoid magazines and popular web sites.

The bibliographic information above is proper MLA format (use whatever style is appropriate in your field) and the annotations are in paragraph form. Note also that the entries are alphabetized by the first word in the bibliographic entry. If you are writing an annotated bibliography with many sources, it may be helpful to divide the sources into categories. For example, if putting together an extensive annotated bibliography for stem cell research, it might be best to divide the sources into categories such as ethical concerns, scholarly analyses, and political ramifications.

For more examples, a quick search at a library or even on the Internet should produce several examples of annotated bibliographies in your area.
