In the early 1950s, the newly founded RFF convened the Mid-Century Conference, where more than 1,500 leaders could 'exchange viewpoints on important resource issues that appear to be of continuing significance for at least the next generation.' This collection gathers RFF's classic, most enduring works on subjects that have always been on the heart of RFF's research agenda, including how to value and measure the benefits from nature and how to effectively conserve and manage resources in an increasingly interconnected world. The RFF Library Collection brings back landmark books published by Resources for the Future throughout its nearly 60-year history as the pre-eminent research institution devoted exclusively to environmental issues. The Collection offers individuals and institutions the most classic and relevant literature across a range of environmental issues.
