Thanks for the DC chronology link! Although, looking at Wonder Woman on the one you linked, it doesn't seem to even get through her Post-Crisis series - maybe I'm using it incorrectly. I've been referring to
http://dcuguide.com/, which drops off a bit after Infinite Crisis.
For Marvel Chronology I exclusively refer to
http://www.chronologyproject.com/, but it trails off after 2010 for most characters. It's not the most modern of websites (what I wouldn't give to fix it up!), but it matches 99% with Marvel's own Official Indexes, so it's good enough for me
