Seven medical literature indexes published in the United States between 1895 and 1984 were surveyed resulting in a bibliography of 684 medical literature citations regarding chiropractic. A synopsis is presented of the development of both the National Library of Medicine and medical literature indexes. Discussion included tabulated analysis of the citations by index title, years published, languages, and journal titles. Findings included 430 English language citations and 221 foreign language citations with 67 percent of the entries published since 1960. Observations of the demographics of the bibliography show an early period with most citations dealing with chiropractic education, legislation and jurisprudence; a predominant middle period with most citations reporting the adverse effects, complications and methods of chiropractic; and the current period showing a softening in the medical political rhetoric regarding chiropractic to the point of indexing chiropractic literature per se.
