Earth Inspectors


  This page is no longer being updated. For the new version, click here.

This series was started in the late 80s by Edward Packard, the creator of the Choose Your Own Adventure series. The books were published by McGraw-Hill, and twelve were released before the series ended. In the books, the reader is an alien trying to learn about the Earth. The ultimate result is rather similar to (but weaker than) the Time Machine series; each book presents the reader with a mission and leads to only one ending.

The information on this page is as complete as my collection will allow. If you find any errors or have a copy of a book I'm missing, please send an e-mail to demiankatz@gmail.com.


1. America: Why is There an Eye on a Pyramid on the One Dollar Bill?
This book is not part of my collection.

 2. Amazon: Where Do Fish Swim Through the Treetops?
Author: Sara Compton
Illustrators: Mona Conner (cover), Barbara Carter (interior)
First Published: 1988
ISBN: 0-07-047994-1
Length: 101 pages
Number of Endings: 1
Library of Congress Summary: As an Earth Inspector, the reader is called upon to save a friend lying near death after returning from the Amazon.
My Thoughts: This isn't a very good book... The text segments are badly paced (and annoyingly full of the word "Earthling"), the mystery isn't very interesting, and even though the plot branches quite a bit, the lack of multiple endings pretty much removes the replay value after the first time through.

 3. Olympus!: What is the Secret of the Oracle?
Author: Edward Packard
Illustrators: Mona Conner (cover), Barbara Carter (interior)
First Published: 1988
ISBN: 0-07-047995-X
Length: 101 pages (plus glossary)
Number of Endings: 1
Library of Congress Summary: As an Earth Inspector, the reader travels back in time to Greece in 400 B.C. to search out the Oracle of Delphi and discover the secret of her powers.
My Thoughts: While this book gains some points for a slightly non-linear feel, it's still not too great. Due to the inclusion of a "data bank" and the use of time travel in the plot, this very closely resembles a rather weak Time Machine book.

 4. Australia: Find the Flying Foxes!
Author: Louise Munro Foley
Illustrators: Mona Conner (cover), Barbara Carter (interior)
First Published: 1988
ISBN: 0-07-047996-8
Length: 101 pages (plus glossary)
Number of Endings: 1
Library of Congress Summary: As an Earth Inspector sent to find the real meaning of an Aboriginal legend, the reader travels back 200 years in time and is drawn into the conflicts between the white settlers and the native Australians.
My Thoughts: This book is definitely above average for the series... While its value as a game is still fairly low, it's more interesting and somewhat better written than many of these books.

 5. Venice: Who Are the Three?
Author: Sara Compton
Illustrators: Mark Frueh (cover), Barbara Carter (interior)
First Published: 1988
ISBN: 0-07-047997-6
Length: 97 pages
Number of Endings: 1
Library of Congress Summary: The reader is called upon to find and rescue Zy, a fellow Earth Inspector, who has been captured and brought before "The Three," the most dangerous personages in Venice.
My Thoughts: Like Sara Compton's earlier book in this series, this book is a rescue mission, and a rather uninteresting one at that. The amount of text between choices is excessively large and many good opportunities for story branches are missed.

 6. Africa: Where Do Elephants Live Underground?
Author: Edward Packard
Illustrators: Mona Conner (cover), Barbara Carter (interior)
First Published: 1989
ISBN: 0-07-047998-4
Length: 104 pages
Number of Endings: 1
Library of Congress Summary: As an Earth Inspector, the reader tries to find the strange place where elephants live underground.
My Thoughts: This is a rather long book; it seems designed to make sure that you go to most of its locations before you finish it. This actually sort of makes sense within the context of this series; since there's little replay value you might as well get through most of the book the one time you read it... Of course, this makes one wonder why the book is a gamebook in the first place. In any case, apart from this, the biggest notable thing about the book is the fact that it has a certain amount of series continuity, picking up where the last book ended.

 7. China: Why Was an Army Made of Clay?
Author: Richard Brightfield
Illustrators: Mark Frueh (cover), Madeline Sorel (interior)
First Published: 1989
ISBN: 0-07-047999-2
Length: 102 pages (plus glossary)
Number of Endings: 1
Library of Congress Summary: As an Earth Inspector, the reader tries to solve the riddle of the army made of clay.
My Thoughts: This book is slightly above average for the series; it feels rather pointless, but at least it's well paced. It's also interesting to compare this to the twenty-first Time Machine book, Caravan to China, which visits some of the same periods of history but presents them very differently.

 8. U.S.A.: What is the Great American Invention?
Author: Richard Brightfield
Illustrators: Mona Conner (cover), Barbara Carter (interior)
First Published: 1989
ISBN: 0-07-048000-1
Length: 105 pages
Number of Endings: 1
Library of Congress Summary: As an Earth Inspector, the reader tries to uncover the mystery of the great American invention.
My Thoughts: This is a weak book... While the use of a companion character (Teega, a first-time Earth Inspector) is an interesting idea, the book as a whole is predictable and condescending.

9. Europe: Why Was a City Built to Capture a Castle?
This book is not part of my collection.

 10. Japan: How Do Hands Make Peace?
Author: Carolyn Meyer
Illustrators: Mona Conner (cover), Barbara Carter (interior)
First Published: 1990
ISBN: 0-07-048005-2
Length: 105 pages
Number of Endings: 1
Library of Congress Summary: As an Earth Inspector trying to solve a riddle, the reader encounters ancient samurai warriors, copes with strange customs, and gets lost on Mt. Fuji.
My Thoughts: I first read this book more than a decade ago, when it had just come out and I found a copy at the library; for some reason, I have happy memories of staying up late reading it, though the actual content of the book disappeared from my mind until had an opportunity to read it again after purchasing it from the library's clearance section. Funny how I ended up owning so many of the books I used to borrow from the library... As it turns out, it's a pretty good book. It does a good job of reinforcing the fact that the reader is supposed to be an alien, and it also presents a lot of interesting facts about life in Japan. It's not perfect, however... For one thing, I suspect that Japanese readers might find some aspects of the story a bit insulting (it seems rather critical at times). Additionally, the gameplay isn't very interesting, though that's to be expected from this series; the interactive element is rather underused, and this wouldn't feel much different if it were a completely linear book. Still, it's a more interesting read than many of the other Earth Inspectors books.
Errata: On page 22, the message "go on to the next page 18" should simply read "go on to the next page."

11. England: What is the Secret of the Stones?
This book is not part of my collection.

12. Russia: What is the Golden Horde?
This book is not part of my collection.
