Wikipedia:Articles for deletion/List of members of the American College of Medical Informatics
It's not an indiscriminate directory (it only includes the members who have Wikipedia articles rather than a copy of the entire membership listing), so  doesn't really apply. It describes a very specific collection of people, but there are enough of them that are already notable to make for a list of reasonable length, so I don't see the problem with  either. It provides extra information beyond what a category can provide (the election years), so it also makes more sense as a list than a category. I think this is ok according to
