An annotated bibliography is a list of book, article, and document citations. The annotation follows each citation with a brief (typically around 150 words) descriptive and evaluative text. The annotation's objective is to inform the reader about the relevance, correctness, and quality of the sources quoted. It also alerts the reader to any inconsistencies or conflicts between the sources. Annotated bibliographies are usually included as part of larger works such as books or journals. These works may have many different titles including lists, guides, and reference manuals that are often used by scholars when writing papers. Typically, an annotated bibliography includes the following elements: author(s), date published/received, title of work, publisher, location where the work was found, and an indication of its relevancy to the scholar's topic. Annotation should be limited to only these elements; any additional information can be stated in the body of the paper using appropriate references. For example, if a scholar quotes several sentences from two different sources and then explains why they are important, the last sentence of her paper would look like this: "For further information on this subject, see John Smith's book, "Essential English Language Skills," page 93." Books, articles, and documents used as source material for research papers are called sources. When referencing multiple sources, it is necessary to give credit to each one.
