What is an Annotated Bibliography?
An annotated bibliography is a list of citations for various books, articles, and other sources on a topic. The annotated bibliography looks like a Reference page but includes an annotation after each source cited. An annotation is a short summary and/or critical evaluation of each source.
The purpose of an annotated bibliography is to provide an overview of the research that has been completed on a topic. It enables the reader to determine the quality of sources and decide whether a particular source will be useful in researching a given topic. Rather than just listing the sources, an annotated bibliography allows you to evaluate and assess the sources that will be used to support your research.
Creating an Annotated Bibliography
A typical annotated bibliography consists of the following elements:
Citation – The full bibliographic citation of the source comes first in MLA or APA format as appropriate.
Summary – The summary should be 1-2 paragraphs that concisely discuss the major arguments and conclusions of the work without directly quoting the source. This demonstrates the author’s understanding of the source’s overall purpose and content.
Evaluation – 2-4 sentences evaluation of the source explaining its overall value and relevance, including its strengths and weaknesses or what type of audience might best benefit from the source. For a scholarly work, the evaluation will likely discuss the source’s thesis, methodology, and perspective, while for a general audience work, the evaluation will examine its accessibility and style.
Thesis Statements and Research Goals
When creating an annotated bibliography, it’s important to first clearly identify your topic and formulate a thesis statement about the issue or problem being researched. This establishes the scope and focus of your research and determines which kinds of sources will be most relevant for your annotated bibliography. Your thesis statement should reflect your overall research goals and the important themes, theories, debates, methodologies or perspectives surrounding the issue. This guides which sources to include and how to structure your annotations.
Some key aspects annotations should address based on research goals include:
The central argument or thesis of each source
Relevant background information provided
Methodology and types of evidence used to support claims
Major conclusions and implications of research
How source relates to or further develops your topic
Credibility of Sources
When evaluating sources for your annotated bibliography, consider factors like publication date, author credentials, publisher or journal, and methodology used. The goal is to select scholarly, credible sources that lend authority and support to your own research. Up-to-date sources and a variety of perspectives are ideal. Credible sources should be peer-reviewed and back up claims with evidence. Too informal or outdated sources are generally not appropriate. Cross-referencing sources against each other and consulting subject experts can help determine credibility.
Annotated Bibliography Structure
Consistency is important when formatting each annotation. Annotated bibliographies usually follow consistent structure, such as:
Citation
Summary of key points (3-5 sentences)
Evaluation of usefulness, credibility, importance to topic (2-4 sentences)
Alternatively, some may summarize first followed by evaluation or integrate evaluation points into summary. Whichever style is used, be consistent throughout document. Each annotation should be 100-250 words. Paragraph formatting provides clarity versus straight summary blocks. Remember the purpose is to both cite and evaluate sources, not just list them. Organizing annotations in the same consistent format allows reader to efficiently grasp summarized information.
Tips for Writing Annotated Bibliographies
Read all sources carefully before writing annotations
Keep entries concise yet thorough in addressing key details
Consider using subheadings to group sources by theme or perspective
Maintain consistent citation format for each entry
Proofread carefully for grammar, spelling and adherence to guidelines
Consult sample annotated bibliographies as models for structure
Have another person review citations and annotations for completeness
Leave annotations open to improvement as research continues to evolve
The annotated bibliography guidelines from Owl Purdue provide an excellent overview of how to construct an effective annotated bibliography according to scholarly standards. Following a clear template and citation format like MLA or APA ensures all sources are consistently and accurately represented. Taking time to summarize and evaluate each source thoroughly will produce a strong foundation for future research on any given topic. An annotated bibliography allows one to grasp a holistic sense of the conversation surrounding an issue.
