The Merck Index is a one-volume encyclopedia of chemicals, drugs and biologicals that contains more than 10,000 monographs, 32 supplemental tables and 450 Organic Name Reactions. Nearly 4,000 of the entries cover drugs and pharmaceuticals, 2,000 describe common organic chemicals and laboratory reagents, another 2,000 cover naturally occurring substances and plants, 1,000 focus on the elements and on inorganic chemicals, and approximately 1,000 pertain to compounds of agricultural significance. Each monograph in this authoritative reference source is a concise description of a single substance or a small group of closely related compounds. In addition, there are more than 700 new and completely revised monographs, thousands of new references, trademarks and uses added to previous edition's monographs. Several hundred discuss endogenous substances and biological agents. There is an expanded focus on "Green Chemistry" and compounds of environmental significance. In addition to revisions and updating, enhancements include embedding the Chemical Abstracts Registry Numbers for title and derivative compounds within the monographs.
