Interpretation is the art of making what is presented meaningful to the audience. This book is useful for anyone who wants to get others interested in a subject, whether it is for a presentation, an art exhibit, or the local park's visitor center. If an exhibit, lecture, presentation, or tour does or does not get you interested in the topic, this book will explain most of the reasons why. This is all sound wisdom, offered in the context of museums and national parks. It's easy to read and engaging, employing the principles within.
I. Talk about what is being desplayed/described to the personality or experience of the visitor.
II. Interpretation is revelation based on information.
III. Interpretation is an art.
IV. The goal is provocation, not instruction.
V. Try to present the whole instead of the part.
VI. Don't just dumb it down for kids.
Tilden elaborates on these beautifully, with nice examples.
After reading this book not only do I know how to improve upon my own interpretation, but I can critique other interpretation and at least know when to appreciate a good display when I see one. Just remember that there are more than 6 principles. Use this book to start thinking about interpretation as a skill and an art, instead of the bible of interpretation.
Interpretation for the 21st Century: Fifteen Guiding Principles for Interpreting Nature and Culture is an updated version recommended to me but I haven't read it yet.
