GEOG 442/542 Sustainable Cities: Grey Literature

Some reliable, scholarly literature does not go through a traditional peer-review process. These materials include reports, white papers, and other research and are referred to as grey literature because they are not commercially published. Rather, this literature is published by non-profits, research agencies, governments, etc. It can be helpful to supplement your searches by looking at institutional and agency websites, and by searching databases containing citations to working papers.
