Encyclopedia of Global Resources

Gr 9 Up—A revision of the publisher's 1998 Natural Resources, this set adds a volume and 143 new articles (for a total of 581 entries). The frequent graphs, charts, and tables have been updated or replaced, and 110 new items included. Initially, this set may be used most by those researching the 2010 Gulf of Mexico oil spill. While publication was prior to this event, students will find plenty here for their reports. Along with background on how oil is formed, the authors provide in-depth information on the oil industry and past spills, and the "Oil and natural gas drilling and wells" article describes various methods of extraction and associated dangers, including blowouts. There's plenty more here, however, as the set also covers other resources and events, ideas, technology, people and groups, legislation, and countries. The sometimes complex but always clearly written pieces range in length from approximately 500 to 3000 words and are subdivided using headings such as "Category," "Where Found," "Primary Uses," and "History." Many of the relatively few black-and-white photographs are token. However, this resource will find uses in ready-reference and for reports on subjects as diverse as chemistry and social studies. Adding to its value is complementary access to a corresponding e-book, available until 12/31/11.—Henrietta Verma, School Library Journal
