Ok, folks. We have to get serious.
That means a real database of out-of-state potential.
That means:
1) application email/website/whatever
2) main library website
3) OverDrive website
4) Statistics (which could be updated automatically?)
We need an automated process to find out which library has which volume available.
Automated holds/wish list/recommended would be an advanced option.
Hmm...
