From the Rachel Carson Center for the Environment and Society (a non-profit organization created by the University of Munich and the Deutsches Museum) comes the Environment & Society Portal. This portal aims to serve as a "gateway to open-access resources about human participation in, and understandings of, the environment." This rich collection of resources includes archival material, short essays, multimedia material, and websites. Best of all, this collection is thoughtfully arranged so as to be engaging and accessible to scholars and educators as well as interested members of the general public. One highlight of the portal is the Virtual Exhibitions (available via the contents tab), where portal materials are grouped according to a specific theme or event. For example, one virtual exhibit explores the history of water in Bogota, Colombia through photographs, historical cartography, and primary documents. Visitors to the Environment & Society Portal who are interested in learning more about a specific topic will also want to check out Arcadia, a series of short, peer reviewed essays about a variety of topics related to environmental history. Portal material can also be explored via a number of exploration tools - be sure to check out the timeline tool (in beta as of this write-up), which was created using the Wellcome Library's open source timeline.
