This book is a "BIG" (the size of a regular piece of paper) size - Coil binding is used to allow for easy page flipping with no binding.

This website also has this book in "mini" size (half the size of a regular sheet of paper). A popular size to carry anywhere (briefcase, large pocket, purse) but the print is large enough for easy reading.

The Color covers are laminated for weather protection.
