Brian T. Johnstone has an article in the March 2017 Computers in Libraries about setting up his ILS, SirsiDynix, to support lending from the art department at his university. It isn't a directly applicable situation but it certainly got me thinking about ways we can support other law school departments. He was able to create a "mini library" using his ILS; one obvious challenge to overcome is setting up the resources so they don't get lost or become clutter in your discovery layer.
As we think about ways to collaborate with other law school or organization departments, ideas like this keep our creativity going. We just need to be careful with how we go about it so it's actually useful to the new group without making life more difficult for our existing patrons.
