The McGraw-Hill Encyclopedia of Science & Technology presents pertinent information in every field of modern science and technology. The 7100 articles are arranged alphabetically in the 19 text volumes. The 20th volume contains the indexes and ancillary materials. Broad survey articles are available for each of the disciplines covered; even readers with little prior knowledge of that discipline will find the basic concepts covered in these articles. From the survey article, the reader may proceed to more specialized articles using the cross-referencing system. The pattern of proceeding from the general to the specific has been employed not only in the plan of the Encyclopedia but within the body of the articles. Numerous illustrations, both line drawings and images, contribute to the utility, clarity, and interest of the test. Most of the articles contain bibliographies citing useful sources. - Publisher.
