A bibliography provides readers with the author, title and publication details of a source. An annotated bibliography adds a brief summary, or annotation, about each source (book, magazine, journal, etc.). Placed just below the facts of the publication, the annotation describes the content of the work. When writing the annotation, provide enough information in approximately three to five sentences for readers to obtain a comprehensive understanding of the source's purpose, content, and special value.Be sure to use complete sentences and to avoid wordiness.
Process for Writing an Annotated Bibliography
Using the APA format, here is a sample annotation:
Aroian, J. F., & Rauckhorst, L. (1998). Children and adolescent’s use of summer camp health facilities: A longitudinal study. Journal of Pediatric Nursing, 13(4), 200-209.
Recognizing that "the summer camp health center allows children the freedom and self-responsibility to seek out health care on their own initiative," associated professors, Rauckhorst and Aroian, designed a study that examined the health care seeking behaviors of school aged children. Their descriptive study was based on retrospective reviews of health center logs from three summer camps spanning years between 1977 and 1990. The study provides insight about the scope of practice for nurses in camp settings. Specifically, the research examined camper motivation for seeking health care related to accident/injury, communicable diseases, discomfort problems and psychological concerns. The authors compared trends based on age and gender. Limitations of the study include the non-random sample and the use of the health center log as the only source of data about the camper's health seeking behaviour. This article was source of ideas for improving camp practice and suggested avenues for future research.
