Hi Angie!
I've run about a year's worth of Anime Clubs at our library here in Adrian, and we used Crunchy Roll's "Library Outreach" instructions to keep things going. The link for the instructions is
here.
Basically, follow the instructions. Be aware that Crunchy Roll doesn't always get back to you expediently, but I've never had to wait any longer than a week for response from their support staff. It's super easy, you give them the info about your club and your library, and they'll send you info in return about your FREE All-Access Crunchy Roll subscription. Both times I requested this, our library account was award 180 FREE days.
As far as I know, this is one of the only/safest ways of legally streaming most anime. It worked for us, super easy. Hopefully it'll work just as well for you!
Please feel free to email me for further details, if you'd like. Good luck and have fun!
