It isn't clear what you want to do.

Thank you for your reply. Sorry for my lack of clarity. I’ll do my best to fill in the blanks.

Do you want to classify the book as above except if the book is PDF? Any other formats? What happens if a book has multiple formats?

I only really have three formats in my Calibre library; I have PDFs, epubs, & kepubs. There have been times that I have briefly had an additional, but that’s really only in the process of conversion, where in the original will then be deleted afterwards. The books that are PDFs are only PDFs. They don’t have any other formats in that entry in Calibre. The books that are epubs are also kepubs. So yes, all books that aren’t PDFs should be in those categories with the exception of those that have specific tags in the tag browser and I’ll get into that answer next.

You don't want to classify if the book has one of a set of tags? Is that set subject to change?

I have a very limited usage of the general tag column on purpose. I really only use tags as a way of setting apart a small number of books, such as graphic novels, cookbooks, and reference books. Books that, for the most part aren’t just something someone will sit down and read. That it really isn’t subject to change as far as I can foresee. While it is possible I would add an additional entry to that item the list has been fairly static for a significant amount of time and if I needed to add a new tag in there, I would also update this template program.

What happens if a book isn't classified?

Based on my understanding from the original Reddit page where I got this program, it used a single space in certain situations, and seemed to state that Calibra would ignore single spaces as a category.

Does your classification template work (produce the wanted answer) for all books that should be classified?

At this point, it does other than it includes works that I’d prefer not to include. For example, a cookbook isn’t really a novel.

Thank you for your help.
