The work presents a systematic survey of Native American pictographic and ideographic practices, gathering reproduced sketches, photographs, and transcriptions from diverse tribes and media. It classifies recurring motifs and graphic conventions, explores functions such as mnemonic records, calendars, and ceremonial notation, and discusses techniques of inscription on rock, hide, bark, and portable objects. Interpretive challenges, variation across regions, and methodological approaches to reading and comparing signs are considered, with numerous illustrative plates used to support typologies and comparative readings.
