Current studies, reports and other writing on green roofs can often be found in journals, and newspapers. The specialized databases suggested here can be used to identify articles on the subject and are recommended for researching green roofs and living walls. Both journals and databases may be freely available (open access), or they may be available only through paid or subscription-based means.
The subscription resources marked with a padlock are available to researchers on-site at the Library of Congress. If you are unable to visit the Library, you may be able to access these resources through your local public or academic library.
