I need a word which could be used instead of "series" when we talk about books, movies, computer games. The word should have distinguishable singular and plural forms.
An example passage:
My favorite book series (plural) are Harry Potter and The Lord of the Rings.
The Lord of the Rings series (singular) consists of 3 novels.
I'm going to use "set"/"sets", but I'm not sure it is the best possible option.
