Maintained by the Peace & Conflict Studies Program at the University of Toronto, this database has potential as a powerful research tool for those studying the relationships between environmental stress and violent conflict in developing countries. The database contains information on (but not the text of) over 20,000 items, including books, journal articles, papers, and newspaper clippings. Users may conduct searches using keywords, names, titles, or a special coding system developed to permit "complex Boolean searches of the Database to produce subsets of items relating to specific issues." Typical search returns include author, title, publisher, date, and comments which vary in length. The authors stress that most items in the database can be found through local research libraries; however, they do offer limited assistance in locating and reproducing some materials.
