Perhaps this idea could be tweaked for libraries: Ask the question“What’s Your Favorite Green Thing to Do for you Community/Library/Campus” and use it as PR for the library. “Green” prizes can be awarded for unique ideas. Promote the library’s collections of educational information and ideas from all types of your digital and print resources. Include local/campus sustainability related speakers to expand the idea to a program or event. Ask green community groups and companies for donations, sponsorship, or partner together to create an event. This might be a great way to build networks and relationships locally while advocating green practices and involving all your users and supporters for a fun summertime experience @ your library.
I’d love to hear if any libraries are doing any such event or program so please add your comments!
