An annotated bibliography is a list of resources with citations related to a particular topic or arranged thematically that include a brief descriptive or evaluative summary. The annotated bibliography can be arranged chronologically by date of publication or alphabetically by author, with citations to print and/or digital materials, such as, books, newspaper articles, journal articles, dissertations, government documents, pamphlets, web sites, etc., multimedia sources like films and audio recordings, or documents and materials preserved in archival collections.

NOTE: There are a variety of strategies you can use to critically evaluate a source based on its content, purpose, and format. A description of these strategies can be found here.
There are two good strategies you should use to begin identifying possible sources for your bibliography--one that looks back into the literature and one that looks forward.
Your method for selecting which sources to annotate depends on the purpose of the assignment and the research problem you are investigating. For example, if the research problem is to compare the social factors that led to protests in Egypt with the social factors that led to protests against the government of the Philippines in the 1980's, you will have to consider including non-U.S., historical, and, if possible, foreign language sources in your bibliography.
NOTE: Appropriate sources to include can be anything that has value in understanding the research problem. Be creative in thinking about possible sources, including non-textual items, such as, films, maps, photographs, and audio recordings, or archival documents and primary source materials, such as, diaries, government documents, collections of personal correspondence, meeting minutes, and official memorandums. Consult with a librarian or a writing center if you're not sure how to locate these types of materials for your bibliography.
It is important that the scope of sources cited and described in your bibliography are well-defined and sufficiently narrow in coverage to ensure that you're not overwhelmed by the number of potential items to consider including. Many of the general strategies used to narrow a topic for a research paper are the same that you can use to define the scope of your bibliography. These are:
The format of an annotated bibliography can differ depending on its purpose and the nature of the assignment. Contents may be listed alphabetically by author or arranged chronologically by publication date. If the bibliography includes a lot of sources, items may also be subdivided thematically, by time periods of coverage or publication, or by type. If you are unsure, ask your professor for specific guidelines in terms of length, focus, and the type of annotation you are to write.
Your bibliography should include an introduction that describes the topic or subject area covered by the bibliography, explains the method used to identify possible sources [such as databases you searched], the rationale for selecting the sources, and, if appropriate, an explanation stating why specific types of sources were deliberately excluded. The introduction's length will depend generally on the the complexity of the topic and the variety of sources.
This first part of your entry contains the bibliographic information written in a standard documentation style, such as, MLA, Chicago, or APA. Ask your professor what style is most appropriate, and be consistent! If your professor does not have a preferred citation style, choose the type you are most familiar with.
The second part should summarize, in paragraph form, the content of the source. What you say about the source is dictated by the type of annotation you are asked to write [see above]. In most cases, however, your annotation should provide critical commentary that examines the source and its relationship to the topic. Things to think critically about when writing the annotation include:
Annotations can vary in length, from a couple of sentences to a couple of pages. However, they are normally about 300 words. The length will depend on the purpose of the annotated bibliography [critical assessments are generally lengthier than descriptive annotations] and the type of source [e.g., books generally require a more detailed annotation than a magazine article]. If you're just writing summaries of your sources, the annotations may not be very long. However, if you are writing an extensive analysis of each source, you'll need to devote more space.

In lieu of writing a formal research paper, your professor may ask you to develop an annotated bibliography. You may be assigned to write an annotated bibliography for a number of reasons, including: 1) to show that you understand the literature underpinning a research problem; 2) to demonstrate that you can conduct an effective and thorough review of pertinent literature; or, 3) to share sources among your classmates so that, collectively, everyone in the class obtains a comprehensive understanding of key research about a particular topic. Think of an annotated bibliography as a more deliberate, in-depth review of the literature than what is normally conducted for a research paper.
On a broader level, writing an annotated bibliography can be excellent preparation for conducting a larger research project by allowing you to evaluate what research has already been conducted and where your proposed study may fit within it. By reading and critically analyzing a variety of sources associated with a research problem, you can begin to evaluate what the issues are and to gain a better perspective on what scholars are saying about your topic. As a result, you are better prepared to develop your own point of view and contributions to the literature.
In summary, a good annotated bibliography...
In addition, writing an annotated bibliography helps you develop skills related to critically reading and identifying the key points of a research study and to effectively synthesize the content in a way that helps the reader determine its validity and usefulness in relation to the research problem or topic of investigation.
