Quick Summary

An electronic encyclopedia is a digital reference work that presents information through various technologies. Initially developed on CD-ROM, these encyclopedias evolved to include online versions, leveraging personal computer systems and telecommunications networks for distribution.12

Key features of electronic encyclopedias include:
* Vast Storage Capacity: They can hold significantly more information than print versions at a lower cost.12
* Enhanced Accessibility: High-speed search software allows for quick retrieval of information based on specific queries, in addition to traditional indexes.12
* Multimedia Capabilities: They incorporate animated graphics, sound recordings, and video to supplement text and images, offering a richer user experience.12

Microsoft's Encarta was a prominent example, evolving from a CD-ROM product to an online service before being discontinued in 2009 due to the rise of free online resources. Other notable examples include Britannica Online and the collaborative, open-source Wikipedia.31
