    • 1993, Ordway Hilton, Scientific Examination of Questioned Documents[1], →ISBN, page 395:
      No scientific examiner would select only chance variations to establish nonidentity of two specimens when the fundamental points of identification stamp them as originating at a single source.

    • 1995, Thomas A. Whitelaw, Introduction to Abstract Algebra[2], →ISBN, page 99:
