We hear about both sides of colonial history so often these days that a book like "Bury My Heart at Wounded Knee" can seem a little trite, even biased towards the Indian side of the story. In fact this book is 30 years old and is the book that _produced_ this shift in perspective--before its publication the Indian side of the story was never part of the mainstream culture in the first place. Still an important work on early American history, "Bury My Heart at Wounded Knee" is also seminal in its own right. Read it by all means; if you're already familiar with American Indian history, you'll have the proper context to put it in, and if you're not, you need the wake-up call.
