On Tibiopedia is history of boosted monsters. It's something new but you are able to see all bosted monsters.
Boosted monsters history HERE
News from Tibia website about this update - here
There are two more fansites that display the history of boosted creatures in ways that are easier to navigate, in my opinion:
The fansite Rookie.com.pl has a history of all boosted creature in this link.
It's interesting because you have a button () next to the creature that redirects to QA searching it's name.
