When writing your annotation, make sure it includes all the necessary components. They may vary in different formats, although the typical components are the following:
- The purpose of the work. Your annotation should provide the main purpose of your research work.
- The target audience. It should also define what audience may find your research paper useful.
- The topicality, usefulness and relevance of the research paper. Explain briefly why and how your research can contribute to the relevant area of science.
- The background of the author of the work cited.
- Conclusions which the author achieved in the cited work.
- Conclusions which are achieved by you personally within the research process.
Concerning the format of the annotated bibliography, it may vary depending on the requirements of your professor. He may have defined a certain style guide that you need to use. However, if you have no requirements, you need to consult additionally in regard to this issue. If this issue is up to you, learn the instructions provided by citation style guides like Turabian, APA, MLA, Chicago, etc. As a rule, annotated bibliographies have alphabetically ordered items written in accordance with the author's name. You may find in the citation guide which information is appropriate to include in this part of research paper for every item. Anyway, the annotated bibliography has to be written right after the citation or below.
On the other hand, the annotation may also be organized in such orders as: chronological (by the date of publication, as well as by the period of subject, such as era, century or other historical period); by subtopic, if there are subtopics in your research paper; by formatting style (for example, books, article, media-files, web-pages and so on); by language used by the author for writing his work.
