The Official Marvel Index to the Avengers

A six-issue Marvel series from the mid-1990s, The Official Marvel Index to the Avengers served as a comprehensive reference guide to Earth's Mightiest Heroes. Rather than telling new stories, it cataloged the team's history, character appearances, and key plot points up to that era, offering fans a structured look at the sprawling Avengers mythos. Primarily a resource for dedicated readers, it stands as a practical snapshot of the franchise's continuity before the modern age.
