Village Library
The Mabe Village Library is located on the west side of Mabe Village, and holds a number of books availible to read. These books are:
Selecting the Item that's Right For You
Auto Map and Memo Guide Book
Secrets of the Whirling Blade
How to Handle Your Shield Like A Pro!
Fun With Bombs
The Properties of Warp Holes
Atlas of Koholint Island
Dark Secrets and Mysteries of Koholint
Most of these books are really just for beginners starting out in the game, but the one you'll want to read is that last one on the list. You cant read it right away though, you need the Magnifying Glass first. It contains a series of arrows pointing in different directions, this is the way you must go once you get inside the Wind Fish's Egg. So you basically need to read this book to finish the game, unless you get really lucky.Also, the arrow pattern changes from game to game, so you must write it down.
