I'm trying to sort my books in calibre. I've read the "managing subgroups of books, for example "genre" ", but I'm just not getting it.
I'd like to start with Fiction/Nonfiction, sub-divide from there. (similar to Dewey system, not as detailed)
I guess I'm not understanding some basic facts. I see that I use the tags to identify the individual books, and that books can have the same tags, but I don't get how to actually DO it in the tag browser.
When I open it up, there is a 1, and the letters.. I thought the letters would be authors or titles, but in A, I have 3 entries, only 1 A name. (file attached)
I don't know what to do the tag #1- I thought I could attach a name to it, but I haven't figured out how to, if that's the case.


Thank you for all help !
