Both the graduate school office and the office of career counseling at my college have this book, and the staff guard it jealously--with good reason. It clearly describes each foundation and their guidelines for the type(s) of grants they make. In perusing this book, I didn't find a guide to writing a grant (probably because I was seeking foundation information), though other excellent books on how to do so exist elsewhere. If you want to cut to the chase, and save time and energy in targeting the right foundation(s) to meet your need, the hefty pricetag is worth your investment.
