Comics by Year
Standard sorting (in chronological order) lets you view comics the way they were initially published. This means that comics from different series will alternate with each other.
Comics by Series
Sorting by series lets you read comics from a specific series only — excluding all the other issues that were published around the same time.
Comics by Theme
If you are interested only in comics on a specific topic, you can sort issues by theme.
Comics by Hero
If you are interested only in comics with a specific character, you can sort issues by hero.
