From the Introduction:

We hope that Ojibwe people will find this phrasebook helpful in learning, teaching and speaking Ojibwe.
We hope that the speakers of other tribal languages will want to create phrasebooks and other books in their languages.
We hope that this book will be helpful to people who live, work, and travel among the Anishinaabeg.
We  hope that it will be interesting to students interested in learning languages.

Sincerely,
Jim Clark & Rick Gresczyk
