Items with asterisks (*) are pre-order items.
N = New listing appearing on list for first time
R = Item returning to the list after having been off for 1 or more weeks
* Huge movement for The Walking Dead, possibly tied to the announcement that's it's being developed as a television series for AMC.
* Highest debut goes to Jonathan Hickman's Pax Romana. For a collection by a non-name (though very talented) creator and not featuring an established character or franchise, this is quite impressive.
* We may be beginning to see the start of a university effect, where GNs that are assigned as reading in college classes take a bump up at the start of the semester. This would affect books like Maus, Persepolis, Understanding Comics, and Watchmen. Stay tuned over the next few weeks to see if this holds true.
* Is Green Lantern DC's new Batman?
* A GI Joe volume squeaks in at #49, showing that just because you have the top movie in the country doesn't mean that it will translate to big comics sales.
* I added in the 'R' code to differentiate items which are returning to the list, as opposed to items which are appearing on the list for the first time.
