Bibliographies are lists of works organized around a topic, while guides to the literature are systematic introductions to the literature of a field.
Literature reviews are a handy way to get quickly into the scholarly literature. A typical literature-review article will provide a narrative that identifies and describes dozens of journal articles and books.
Use dictionaries and encyclopedias to learn quickly about the state of research on your topic. A good encyclopedia article should describe major themes, current research fronts, and controversial areas; it should also provide a brief bibliography of classic, important, or definitive works on your topic.
Handbooks generally offer chapters on specific aspects of a topic. As a collection of essays, the handbook's chapters should provide a broad overview of the state of research; individually, chapters may be narrowly focused.
