Reference books: From 1969-2001, the Institute produced dozens of reference books, several in multiple editions. Flagship titles were:
The California Handbook (eight editions), the standard resource guide to all aspects of the state, which Sunset Magazine called “an astonishing compendium,” and about which the Los Angeles Times wrote: “No other contemporary guide covers so much California ground.”
The World Directory of Environmental Organizations (six editions), which Booklist (American Library Association) called "an essential purchase for academic institutions with environment-related curricula." The most-visited page on our Web site is a 2,000-word essay that originated in the World Directory, “About Environmental Organizations & Programs.”
Other topics covered by Institute reference books included California environmental law; California legislative and congressional districts; organizations concerned with California’s environment, water, energy, ethnic groups, toxic materials, and transportation; and such national and global topics as energy, population, and food supply. Reviews were positive. A book on energy earned Library Journal’'s designation as one of the “best reference books of the year.”
Research reports and conference proceedings: Numerous publications have resulted from Institute and related IUCN projects. Most are now issued in both print and online form.
Many of the printed books and reports have been published by the Institute. Others have been co-published with such other organizations as IUCN, Earthscan (London), Development Alternatives (New Delhi), and the World Future Society. Articles resulting from the Institute’s work have appeared in academic and professional journals.
