Professor Harvey has produced a lucid, precise and accessible guide which will be invaluable to all students and instructors who are involved in the writing of papers. Technical conventions are set out clearly and the basic principles illustrated intelligently. The author has a wealth of experience in the field and I have yet to come across a referencing issue which this little book has not addressed. Most importantly, this guide not only gives one peace of mind, but shrewd advice on the most effective ways to integrate sources. As an International Baccalaureate Coordinator, I have often had cause to refer to "Writing with Sources" and it has never failed my students or me.
