Upon closer examination, the haphazard editing becomes quite clear. There are numerous mistakes throughout the book, which negate any of the positives. After all, if you can't trust all of the facts provided, then truly you can't trust any of the facts. Do not blame the authors for these errors. These mistakes fall on the shoulders of the editors and designers who did not take enough care in updating the Marvel Encyclopedia.
When The Marvel Encyclopedia gets it right, it's a nice resource for comics fans. The fact that this doesn't happen often enough is unacceptable. Though it may look pretty when you see it on the shelf, know that the Marvel Encyclopedia is a mess. DK Publishing was sloppy in putting this book together. Too bad it's probably the most important comics-related book they have published.
An essential book both for new fans and for those who grew up loving the comics, The Marvel Encyclopedia is full of artwork, stats, and history for every character in the Marvel Universe. Updates on characters include information from the story arcs of Civil War and Annihilation, and brings fans up to date with the aftermath of Secret Invasion.
