A possible interesting listserv to join: IFLA Environmental Sustainability and Libraries Special Interest Group Mailing List (firstname.lastname@example.org)
This is a discussion list for information professionals who are interested in issues related to sustainable development and libraries. Such issues include: the impact of environmental dynamics on libraries, their activities and the conservation of collections, library environment-friendly management practices, “green” library buildings as well as collection development and diffusion of information that foster awareness about sustainability among both users and professionals. The list is also the communication channel for the IFLA Environmental sustainability and Libraries Special Interest Group.
