Query: Outdated Sources and Colonial Attitude

Marrin's book makes significant use of outdated sources, many before 1970, as well as romantic photographs and illustrations. Although the book is impressive for a young adult audience, with its bibliography and textbook feel, the lack of current scholarship on Sitting Bull is apparent as one reads through the chapters.I would not recommend this book to any age group. The perpetuation of colonial attitudes is prevalent in Marrin's book. As well, the lack of Native voice is apparent. Marrin often negates Lakota spirituality and projects the romantic, utopic Indian with phrases like "Oh no! He was none other than the buffalo god!" The heavy (and skewed) emphasis on war and killing in the middle chapters begs for historical qualification- and makes for barbarism for children who have little frame of reference.This book suceeds in keeping American Indian people in the colonial time warp and does little to portray Sitting Bull in an humanistic fashion.
