How do you organize your library?

I'm going through and reorganizing my library's folder structure. I'm grouping titles by publisher and was wondering how do you organize different series, like ongoing titles, spin-offs, mini-series, events, etc? Do you have any sort of organizational practice that works?

I do mine by title, then by sub-title if they have it, otherwise I do v1, v2, etc.

I also put together titles with shared first word

so

Avengers
- Avengers Academy
- Avengers Assemble
- v1
- v2
