The bibliography enumerates those papers in the open scientific literature through 1963 that deal with ruthenium, and represents a practical attempt to completely record the literature dealing with ruthenium. References are included that report relevant biological, chemical, and physical properties of the metal, its many chemical compounds, or its complexes. The report is arranged in four major parts: Index in which keywords-in-context (KWIC Index) from each title have been arranged alphabetically down the center of the column; Bibliographic citations arranged alphabetically by last name of principal author; Cross-index of all author names arranged alphabetically for all references cited; and Cross-index containing more than 200 U.S. and foreign patents related to uses of ruthenium and offering direct access to the patent literature citations.
