Huey, Dewey, and Louie Duck are present in most of the Carl Barks stories bearing the logos Donald Duck or Uncle $crooge, i.e. primarily the 10-pagers and the long adventure stories. It is interesting to see how Barks developed the nephews over the years. In the first 10-pagers they were mostly intolerable brats but later they slowly turned into good-natured helpers, and in the adventure stories they acted very much as adults in intelligent and responsible ways.
The sub-pages each present 10 examples in chronological order from the mentioned categories focusing on the nephews' changing characteristics in the three main groups of stories. The chosen examples are as diverse as possible within their categories.
