THE CACHE IS NOT LOCATED AT THE ABOVE COORDINATES.
A good friend of mine (trail reader in California) thought that it would be fun to combine the indoors of the library with the outdoors of geocaching. So, I'm bringing her puzzle here to the midwest. Welcome to her world!
The Dewey Decimal Classification System (DDC) was invented by Melvil Dewey. The DDC categorizes nonfiction books by subject matter into ten main divisions which are then further divided into ten subdivisions. The longer the Dewey number, the more specific the subject matter of the book. The DDC is the most widely used classification system in the world--found in libraries in over 100 countries and translated into over 30 languages.
This is the third in a series of Dewey puzzles I'm creating to honor the cache owners of the Omaha area. Do we know these people personally? Probably not. However, we have come to know them by their hides--the type, the container, the placement, the difficulty, etc. For example, most cachers here would agree that I have a fondness for light skirts!
Geocaching is a give-and-take activity and we all depend on the time, energy, and creativity of cache owners to keep our sport alive. If you have not yet hidden a cache, please consider doing so. To those of you who have, thank you!
3omahakids is a busy, busy momma. You think being a momma of three she would be too busy for geocaching but, don't under estimate her she is fast! If a new cache publishes she is hot on its trail. 
She is the best tree monkey I know. The only thing that has her running in the other direction is snakes. She is a self admitted city girl and her hides are exactly that.
In order to solve this puzzle, you do not need to know 3omahakids. But, by simply using her hide titles, determine the correct coordinates for the cache by classifying each subject in the DDC.
