There is a key difference between this chart and the last three Julys: the latest volume of The Adventure Zone is not in the top slot.

The June Superhero chart is remarkable in that there are so many new titles.

We look at the year-over-year trends for Superhero and Author graphic novels, and at a size comparison of manga vs. the other categories.

DC dominated the superhero chart in May, a title tied to a webtoon rose to the top of the author chart, and the manga chart looks like the Top 20 Adult Graphic Novels.

Superheroes were on a roller coaster, manga was on a roll, and it was a good month for Author graphic novels in the book channel.

A movie tie-in(!), comics from Instagram, and the impact of digital manga show up among the bestselling graphic novels by category for April.

Given that the entire Top 20 Adult list was manga, we look at whether the numbers show that other categories shrank.

James Tynion IV has three titles across two charts, and manga readers are diving deep into series they're starting.

The question for our deeper dive is whether categories other than manga saw robust sales as well.

Manga's domination of book channel adult graphic novel sales continued in March, with a near sweep of the top 20.
