These are my libraries:

Apollo
Dawn
DawnConversions (more of a work directory when xferring things from daz<->poser)
Daz Studio (Genesis 1, 2, and Daz only lights/shaders/etc are in here)
Environment (everything from props to buildings and full env+domes ie terradome)
Freebies
Generation 3
Generation 4 Clothing
Generation 4 People
Hair (since I use Netherworks' HCS and transfer hair among figures, it has it's own library)
Lisa's Botanicals (have almost the entire catalog, so she has her own runtime)
Pippin
Poser Lights and Shaders
PP2012 Content
PP2014 Content (these two are probably redundant)
Texture Work
Vehicles
Weapons
zStandalone Figures (z added to the front so it's the last runtime)

I used to have props, buildings, etc all in separate runtimes, but I have so many multi-object sets that I always ended up with props in the architecture runtime and so on. So I just smooshed it all down to one Environment runtime.
