sonic encyclopedia

A Sonic encyclopedia focuses on Sonic’s video-game history, presented as a full-color historical retrospective. It offers in-depth coverage of nearly every game appearance and detailed looks at characters, settings, and storylines.

These encyclopedias are typically published in hardcover and paperback editions.

Page counts in the listings range from about 288 pages up to 1,136 pages.

Listed dimensions vary by edition: heights are around 9–9.2 inches, widths range from about 1 to 7.3 inches, depths from roughly 2.5 to 6 inches, and weights from about 1 to 4.1 pounds. Exact size and weight depend on the specific edition and binding.

Suggested ages in the listings vary: some editions are aimed at teens (approximately 12–17 years), while others are labeled for adults (22 years and up). Individual listings should be checked for the publisher’s recommended age.

Common features are full-color presentation (noted for the Sonic volume), hundreds of historical photos, incisive essays, and extensively revised or updated entries (noted in the music volume).

The listings cover video-game art (Sonic-related content) and music reference material—i.e., game-focused reference and music-focused encyclopedic coverage.

At least one music encyclopedia is described as completely updated, with new entries and extensive revisions that expand the previous edition’s coverage.
