My site has a custom post type 'books' that has custom fields for author, publish date, etc. I'm using taxonomies for 'genre' like mystery, comedy, etc.
I don't know the best way to handle a 'series' of books. For example, a book can be a single book or it can be part of a series of books.
Right now, I have 'series' as a hierarchical taxonomy like:
- Series X
-- Series x book 1
-- Series x book 2
etc.
This works ok, but thinking down the road when I've entered in hundreds of different series, that list where I select the series taxonomy is going to get really long.
(This isn't mine, but same idea hidden link That page shows an author and down below are different series he has written)
