History
The first edition of the Merck's Index was published in 1889 by the German chemical company
Emanuel Merck and was primarily used as a sales catalog for Merck's growing list of chemicals it sold.
The American subsidiary was established two years later and continued to publish it. During World War I the US government seized Merck's US operations and made it a separate American "Merck" company that continued to publish the Merck Index.
In 2012 the Merck Index was licensed to the

An online version of The Merck Index, including historic records and new updates not in the print edition,
is commonly available through research libraries. It also includes an appendix with monographs on organic
named reactions.
The 15th edition was published in April 2013.
Monographs in ''The Merck Index'' typically contain:
* a
CAS registry number
* synonyms of the substance, such as
trivial names and
