I guess now that I have read your responses, my strategy may be as follows:

Tag filter all PDF books.
Export to a folder called "Calibre_PDF"
Then go back to the main library and delete all PDF books from that.
Next Go to Calibre_PDF and delete all books that are not PDF that got transferred over.

That should leave me with a Calibre library containing no PDF books and one with only PDF.

I can then repeat for the other formats, convert those formats that will work well converted to EPUB or MOBI (PDF for instance often doesn't convert well or at all) and merge these books back to the main library deleting all duplicates.

Going forward, I should also import books selectively by manipulating the import filters.

I think the above will work for my main purpose: making sure that I only see books I can import when using a calibre compatible App on my iPhone.

For Mobi, I may export all MOBI books to another library but making sure that the structure of that library leaves all the actual books at top level in the directory so I can browse them by title in one of my file management apps in my iPhone.

Thank you again for your help.
A couple of other points:

1. Do you have any books that are both PDF and Epub/Mobi? If so, you need to decide ahead of time what to do with them. Keep them in both libraries? Default to one or the other library? Decide on a case-by-case basis? Just make sure you don't accidentally lose both formats when you split your library.

2. Calibre can convert between Epub and Mobi pretty seamlessly. One option would be to convert all your non-PDF books to both formats so they're available for both your readers, then keep them both in the same library.
