Handbook

Handbook is a concise reference work that provides essential information on a specific subject or activity, designed for quick consultation rather than exhaustive study. It typically aims to support practical use, decision making, and standard procedures by presenting core concepts, guidelines, and key data in an accessible format.

Handbooks are usually organized around topics, procedures, standards, or checklists. They may include glossaries, diagrams, tables, and easy-to-follow steps. The emphasis is on usability and brevity, allowing readers to locate needed information rapidly without wading through extensive narrative.

The term is used across many domains. Types include field handbooks for professionals, user or product handbooks, style or writing handbooks, and organizational handbooks such as employee handbooks. Scholarly handbooks collect overviews and reference material on a discipline or subfield, while travel, medical, and technical handbooks provide practical guidance for specific activities or settings.

Handbooks differ from manuals in focus and scope. A manual often concentrates on how to operate equipment or perform tasks in a procedural, step-by-step manner. A handbook tends to emphasize concepts, standards, reference data, and guidance that support consistent practice and understanding.

Formats have evolved from print to digital, with many handbooks available as online resources, apps, or searchable databases. Editions are updated to reflect new information, standards, or policies. Overall, handbooks serve as portable, authoritative quick-reference tools that support learning, compliance, and routine work across diverse fields.
