Response Hi thank you for contacted me about understanding my categorization rationales  I was trying to organize the historical societies by state and link such categories within each state so that people interested in a states history or looking for local history organizations can more easily find them  While currently there may only be one article for a state such as Delaware I am sure there are other historical societies in such states and other articles that may be created in the future  Not all historical societies may be notable enough to warrant an article but lists may be created for each state  I could easily see an article created like List of historical societies in Delaware like List of museums in Delaware    In general I believe category names should be consistent across a category and thus Historical societies in  allows for someone to easily find articles for a state of their choice  Also I have linked the categories to organizations in each state and the history of that state which can help someone looking for such an organization  I do not think the categories should be renamed because if future articles are created for such categories that would force another renaming  This way things are more consistent  There are many historical societies in the United States and Ive looked at many websites for them  Some operate museums but many just collect historic documents photos archives or artifacts and some offer genealogical research  There is also a definite distinction between a museum and the historical society which runs the museum  The public may know the museum but not the actual historical society name that runs it or may be looking for information about a town and not be aware of a museum  Some historical societies also operate several museums or historic house museums  Each museum should be categorized separately and the society as well which should be linked to its community of focus  I believe that historical society museums should be a subset of historical societies not the other way around  I have linked them in that way
