Fusion Retro Insider Books is a biannual mini-magazine containing a list of the magazines and books published by Fusion Retro Books over the last six months. This magazine was distributed for Gold-level subscribers with their copies of Fusion.

Fusion Retro Insider is notably one of the only places where Fusion Retro Books printed the publication dates for Fusion magazine.

This is an ongoing collection of Fusion. Some issues are missing, particularly special issues.

For the first 21 issues (and specials through 2021), Fusion came with a collectible trading card featuring the issue's cover art. When available, these trading cards were left inside the magazines and were not cataloged. Some trading cards may be missing.
