I think the 'tripartite' library scheme is pretty much accepted as the best way to do things:
1 - AC Library - PLA - , local HD, can be overwritten in entirety when updated
2 - Office Library - PLA - , located on the server (users can drag a copy locally if they find it slow, periodically updated with an email to notify users)
3 - Project-Specific Library - Loose Folders - we locate all of ours by project number in subfolders on our server under a folder called called 'Project Libraries'
The third one, as a server location makes it easier for me to police, and occasionally run 'no-clone' to make sure people are creating too many unnecessary duplicates/folders, etc.
Oh, and this one:
4 - Archived Libraries - 6, 7, etc...
We have many old projects, old custom libraries, etc. that occasionally need to get loaded. I turn all of these into PLA files, for example, I have a 'no-cloned' PLA of libraries 6 and 7, in case we open and need something of that vintage whose parts cannot be 'found' in our 9 Libs.
