It is a bibliography in which you include a short summary or abstract of sources you are thinking of using for a paper. It is more than a works cited list, which gives only a bibliographic citation for the source. These annotations do one or more of the following:
They provide readers with background information about your sources, who then may want to consult those sources. It's a great way to organize your research by helping you critically evaluate books, journal articles, web sites and other resources.
You should begin your annotated bibliography when you begin your research. This enables you to decide from the start which sources are appropriate for your study. As you read your material, you should identify the thesis statement, take notes, and make a brief outline of what you have read.
Just write the bibliographic entries as you would write any other bibliography, according to the style your instructor wishes. In our case, that will be MLA style.,
You should include one or two sentences summarizing or describing content and one or two sentences providing an evaluation. In evaluation, tell how the source is interesting or helpful to you. List what kind of and how much information is given.
Whole sentences are preferable and at times very concise sentences and simple phrases could be acceptable. Sentence length should vary to avoid short, choppy sentences. Every sentence should convey a maximum amount of information in a minimum number of words. Annotations should be one or two paragraphs long. Annotations should be both offer a summary of the material as well as critical comments. Critical comments should be supported by personal argument or knowledge.
Example of an Annotated Bibliography entry:
Mellen, Joan. Women and Their Sexuality in the New Film. New York: Horizon Press, 1973.
An examination of the treatment of women and their sexuality in modern films is offered in this provocative volume. Using a variety of approaches to her subject, the author offers some controversial conclusions and opinions on films, directors and producers. The major topics explored are sexuality, lesbianism , and sexual politics. One chapter on Mae West discusses her screen image over four decades. In addition to the personalities, many films are analyzed in some detail to illustrate the distorted reflection of women the author finds in them. Photos from about 40 of the films are adequately reproduced and complement the text.
