Here is the official announcement.
Yo Joe has a new GI Joe comic book collector's tool for the collector to use.
It is called the GI Joe Roll Call and it is one massive list of every Joe comic ever released in English. Starting with the Ziff Davis, the Adventure Team, A Real American Hero, Hasbro, Independent, IDW and including Marvel UK, Battle, Battle Action Force and more. (It definitely includes all variant covers)
The list is intended to help the Joe collector who keep what is in their collection straight and for those collectors who keep it in their head be able to put it in a digital form or print it out and keep in their records for insurance purposes.
Joe collector Calvin Chymy put this together based on his collection.

And just realized they speak English in Australia (kidding I know they do) I believe the Australia comics are planned for the international version of the list.
