An annotated bibliography is a list of cited sources (books, articles, websites, etc.) wherein each citation is followed by an annotation (a brief descriptive and evaluative paragraph) of the source. Your annotation of a source should include:
Note: your annotation can include some of these aspects, or even others. If you are completing an annotated bibliography for a class, you should get specific guidelines from your instructor and follow them accordingly.
Many scholarly articles start with an abstract, which is the author's summary of the article to help you decide whether you should read the entire article. This abstract is not the same thing as an annotation. An annotation should be written in your own words and explain the relevance of the source to your particular assignment or research question.
An exploratory essay asks questions and gathers information that may answer these questions. However, the main point of an exploratory essay is not to find definitive answers to a question, but to allow a writer to explore their own perspectives as they investigate a topic, gather information about the topic from different angels, and share that information with readers. It situates the writer in a position of inquiry and exploration rather than attempting to convince or persuade readers on a particular topic. In an exploratory essay, the writer invites the reader into their internal thought process and lays out different and often competing perspectives on an issue or topic in order to better understand it.

It usually has an organizational pattern and combines both summary and synthesis of these sources as they relate to the research question being investigated. A literature review gives an overview of an area of study and should answer questions such as:
If your literature review is a standalone assignment, it should provide your reader with a foundation of knowledge on a topic by collecting relevant research and synthesizing these various sources into a a cohesive summary of existing knowledge.
