I need to create additional libraries to make it easier to sort my music. Libaries will be hosted for now on a PC but will be migrating to an iMac in about a week. I'm just getting back into setting up a computer, Apple Tv and iPhone so not quite sure,
iPhone 6, iOS 10.3.2
Not quite sure I understand what you are asking.
Home Sharing works with the currently loaded Library in iTunes on the computer doing the sharing.
To change the library that is loaded in iTunes on Windows hold the shift key while starting iTunes. You should get a prompt asking you to point to a library (*.itl) file to load.
From there, the library that will appear in an iPhone and an Apple TV over home sharing will be the one that is loaded and being shared.
If you need to change it, then you need to close down iTunes and open it again, and load a different library again by holding down the shift key.
