#duketectivecomics' post though is very good and it should take you a good amount of time to work through that first

hi do you know where I can find a list of all of duke's comic appearances? really struggling to find one!

Unfortunately there's no reading list I've found that encompasses all of his appearances 😔. @duketectivecomics has the closest one with all Duke appearances until Infinite Frontier, but after that it's really difficult to parse out the order of things. You could gamble with the DC fandom page of Duke's appearances which is accurate but out of order, it's a pain but it does tell you all his appearances. After duketectivecomics' list he only has a couple main roles anyway, which seem to be:

Batman: Urban Legends #18-19

Some sporadic appearances in Gotham War

DC Rise of the Power Company

As far as I know that's all, but obviously he cameos a lot in other books. This lack of an updated reading list is bothering me too so I might actually get on that myself, unless someone else has an updated list they want to share (in which case please do!!!). Sorry to not be of more help anon :(.
