Eric Olsen (born August 5, 1958) is the founder, editor-in-chief, and publisher of broad-based online critical magazine Blogcritics and author of local Cleveland blog Cleve-blog.

Over the last 20 years, Olsen has written for print and online publications on a wide variety of topics, from popular media to politics, and his work has appeared in Playboy, Billboard, Alternative Press, Option, The Plain Dealer, the Akron Beacon Journal, Hear/Say, MSNBC.com, Cleveland.com, and other outlets.

[citation needed] His book publications include Networking In the Music Industry (with Jim Clevo, Rockpress, 1993) and The Encyclopedia of Record Producers (with Paul Verna and Carlo Wolff, Billboard Books, 1999), a definitive work in the field featuring original interviews, bios, and discographies of over 500 of the leading producers in recording history.

Timothy White, former Editor-in-Chief of Billboard magazine, called The Encyclopedia "one of the truly indispensable reference books on the annals of the music industry."

Rock historian and author Ira Robbins (Trouser Press) said "this exceptionally well-researched and far-ranging book shines a long overdue spotlight on the often unsung heroes of recorded music."
