What’s harder to answer is the ‘functional’ perspective—is EG appropriate for the workflow of a smaller or even very small library? Supporting the kind of workflow they need, not being overly complex and putting lots of configuration options and/or screens and interfaces in the way that they’d never need. That Kent County library will be demonstrating this with an actual implementation will be huge. If I were a small library considering EG, I’d call up Kent County to get their perspective. And once Kent has implemented and has life proof in front of your eyes, I’d call them up and hear how happy they were with it (and the answer will hopefully be ‘very’).
