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.
Phase I of PubAg provides access for searches of 340,000 peer-reviewed agriculturally related scientific literature, mostly from 2002 to 2012, each entry offering a citation, abstract and a link to the article if available from the publisher. This initial group of highly relevant, high-quality literature was taken from the 4 million bibliographic citations in NAL's database.
Phase II of PubAg, planned for later in 2015, will include the remainder of NAL's significant bibliographic records.
PubAg has been specifically designed to be easy to use and to serve a number of diverse users including the public, farmers, scientists, academicians and students.
The site also provides a link to the NAL Agricultural Thesaurus.
NOTE: USDA has brought AGRICOLA, PubAg, and NALDC together into one search interface. Visit SEARCH from the USDA National Agricultural Library.
