It has been a while since I started thinking of adding an Evergreen ILS driver to VuFind. After months of neglect, last week I picked up the latest version (1.0-RC1) and continued writing it up.
Currently, holdings info from Evergreen is displayed when viewing records and I’ve added support for ILS authentication. Patrons can log in and see their profile info and a list of the items they have checked out. Still unfinished is the ability for them to place a hold, view their current hold requests, and view a list of their current fines (these will be submitted shortly).
Special thanks to NRCan Library for giving me a bit of time to work on this.

We’re also interested in developing a Evergreen driver for VuFind. Have you had chance to work on it any further?

@Lee: Yes, I did work on it a bit further. The missing functionality listed above, the only remaining missing function is the ability to place holds.
The driver has been contributed to VuFind’s JIRA tracker so there’s a possibility that it will be included in the 1.0 release (there seems to be a bit of a delay on that release, though).
