Gr 4-9-This well-designed and informative encyclopedia introduces rain-forest animals, plants, and peoples. Entries also cover a host of related topics, including types of rain forests, locations, and structural features. Both biological processes, such as photosynthesis, and human activities, such as logging, receive attention. Although the entries are arranged alphabetically, the comprehensive table of contents provides a separate "contents by category" list. Color coding identifies the subject of each entry, e.g., yellow for animals. Articles range from one to four pages. A fact box heads entries two pages or longer. Numerous photos, drawings, appropriate maps, and small "in focus" features contribute to the attractive layout. Related entries are suggested at the end of each article. Of course, many topics covered in this source can be found in other print and online general encyclopedias. In fact, some of that coverage may be more extensive for certain topics. However, the focus remains firmly on the rain forest. The authors' concern about environmental destruction is evident not only in articles such as "Erosion" but also in entries about endangered animals. Glossary words are not highlighted in the text, and it is sometimes hard to guess where a topic might appear, e.g., wasps with bees. One would do better consulting the indexes in the final volume. Libraries with limited budgets will need to evaluate their current and potential demand for this specialized resource. Collections seeking thorough coverage of the topic will want it.-Kathy Piehl, Minnesota State University, Mankato Copyright 2002 Cahners Business Information.
