Now I am beginning to understand why I am so out of synch here. Where you are looking for specific, individual Articles, I am looking for an index-type list of all persons under a specific Category. E.g., if I were doing cancer research, I would like an entire list of all persons in the encyclopedia who died from cancer. Then, I can select from the list which persons I would like to study.
Picking from a list of 1000 articles on cancer victims is much harder than picking from a list of a few dozen lung cancer victims. If you specifically want victims of various cancers, the subcatagories are all listed at the beginning of the main category listing.
(NB: The numbers are made up for the purpose of an example, I have no idea how many articles are in each category)
