You know what really, really pisses me off about Marvel?|
They constantly fuck with their numbering system for issues.
Case in point: In 1999, they rebooted Amazing Spider-Man in a new volume (volume 2), therefore restarting at #1. However, from issue 30 of this new volume, it started listing both its Volume 2 number but also it's volume 1 number (what issue the comic would be, assuming the reboot hadn't happened). This carried on until December 2003, when the comic officially reverted back to volume 1 with #500.
It causes havoc when trying to index things, as it means I need a column for volume, a column for issue number, and then a third column for what the issue number would have been had the comic not been rebooted.
And then you get occasions where the title of the comic changes, but the numbering remains as it always was. So Daredevil became Black Panther: Man Without Fear, featuring a completely different cast, but kept the old number. To make things even more confusing, they then released a new comic called Daredevil... but kept it at volume 1.
And some comics, like Captain America or Iron Man, have been put through this chaos at least 5 times.
