I'm currently doing a course entitled "Introduction to Biblical Interpretation". This is one of the books I've read to help me come to terms with the material.
This book appears to be based on a set of lecture notes prepared by Berhof for his students, more than having been written as a book from the beginning.
I found its treatment of the various topics related to Biblical interpreation easy to follow, but covered in less depth than most other books. That said, I think what is said here would be sufficient for many people to come to terms with the core principles.
At the end of many of the sections in the book are a list of references to other books and a set of questions. The questions seem to be based on the other works referenced, but I haven't been able to check as I don't have access to any of the cited works. Unfortunatly, due to the age of this text, many of the cited works are not longer in print.
Many of the questions later on in the book are require you to apply the techniques covered to particular verses; no answers are provided, so it'd be useful for you to have someone who you can ask to check your answers.
