There have been several supplements, etc. "This index contains the entire vocabulary (with the exception of the article and a few particles) of the complete writings constituting the Corpus Hippocraticum. Quotations are in agreement with the edition by E. Littré, which still is the most important edition to date and has frequently been reprinted. Also incorporated were several texts not included in Littré’s edition and those lemmata from the glossaries of Erotianus and Galenus which are not preserved in the Hippocratic writings. But most importantly the material has been supplemented and corrected by means of a systematic evalution of the most recent critical editions and a re-examination of the original manuscripts. This approach combines two advantages: A standardized form of the quotations in accordance with Littré’s edition is coupled with abundant information on the tradition of all the writings, especially those which, until now, have not been republished in a critical edition. – With regard to the presentation of the material the index maintains a balance between a rigid concordance and a dictionary. Organizational principles of primary importance are the grammatical categories and varitations in the meanings of the words; additionally characteristic word combinations ans noteworthy dialectal forms are given particular attention while uncommon words are furnished with a Latin translation. The work is prefaced with an objective introduction in German containing, among other data, a complete list of the Hippocratic writings together with information on their tradition, their different editions, and where possible, their chronology."
