During her term as ALA President, in 1999-2000, Sarah Ann Long initiated a project, in cooperation with Global Learning of New Jersey, entitled "Libraries Build Sustainable Communities." The basic definition of "sustainable" is the use and stewardship of resources today that preserves them for tomorrow, and a sustainable community is one that is healthy and prosperous over the long term. The project defined three components of a sustainable community--Economy, Ecology, and Equity. Economy is the management, or stewardship, of the resources; Ecology is the relationship of the community with its environment, particularly the natural environment; and Equity is fairness to all. "Green" libraries are a subset of this issue.
