What is an annotated bibliography? A bibliography is a list of the sources consulted while doing research about a specific topic. The purpose of the added annotation is to help the reader of the bibliography evaluate the relevance of each source in relation to the research topic.
Common parts of an annotated bibliography:
Citation -- author, title, and publication information given in a specific format (MLA, APA, Chicago, etc.)
Summary -- brief paragraph overview of the source contents.
Annotation -- analysis and evaluation paragraphs. Explain: why you like it, why you're including it, and how it fits or ties into your topic. Important note: not all annotated bibliographies have separate annotations; some only contain a citation and summary for each source. Read your assignment instructions carefully.
