One user in this forum has over 600,000 images in his only catalog, and he has tolde many people that you should use one catalog. Ok, that's fine. But of course I don't think it would be doing anyone any favor not to recognize that there are a number of valid reasons for maintaining separate catalogs. IOW, not a blanket "never" but rather, "it depends". Yes, these are valid reasons for using a separate catalog. I guess I just figured it would be understood I had a valid reason. So to answer your original question, using your operating system you could copy your original catalog as many times as needed. Then open each copy, remove undesired photos (but don't delete from the hard disk), close the catalog, repeat as many times as needed until now you have catalogs to your liking. Excellent. Since posting I found the same advice in another discussion and I think this will be the best way to break up a catalog. Thanks much for your assistance!
