online encyclopaedia
Quick Summary
An encyclopedia is a reference work that provides comprehensive information on all branches of knowledge or a specific subject. The term originates from the Greek enkyklios paideia, meaning "general education".12
Historically, encyclopedias have evolved significantly. Early works were often called dictionaries and varied in size and scope. Modern encyclopedias are typically multi-volume compendiums with detailed indexes, illustrations, and bibliographies.1
The advent of technology revolutionized encyclopedias. Electronic versions, initially on CD-ROM and DVD-ROM, and later as online services, offered vast storage capacity and high-speed search capabilities. These digital formats also enabled multimedia features like graphics, sound, and video, making encyclopedias more accessible and interactive. Online encyclopedias like Britannica Online and Wikipedia have become prominent, offering vast databases and links to external resources.34
