Very dry, but has all the basic information. There are quite a few samples in the book which are all jaw-droppingly boring. If that's how grant writers actually write I'm not sure how grant reviewers survive.
The Everything Grant Writing Book (2nd Edition) by Nancy Burke Smith and Judy Tremore makes grant proposal writing accessible to anyone wishing to write grants. Smith and Tremore outline the importance of grants to nonprofit organizations.They discuss the process and offer examples to simplify the process of writing grant proposals in an easy to read, easy to understand manner. The Everything Grant Writing Book is a great resource for anyone wishing to write grant proposals because it takes the intimidation out of the process for the novice without denying the amount of work writing grants requires. I wish I'd had this book when I wrote my first grant proposal.
