Electronystagmography and Videonystagmography:
ENG/VNG, 2nd Edition by Devin L. McCaslin

The second edition of this book by Devin L. McCaslin is an excellent resource to add to one’s personal (or professional) library, whether a student, novice audiologist, or experienced audiologist. This book is written concisely yet still can dive deeper into important topics (such as some of the more technical aspects of performing a VNG/ENG).
As a newer instructor of doctoral-level students for vestibular assessment and management, I enjoy using this book for the material in my lectures and as a resource for the students. In addition, compared to some of the other great vestibular books, this book has the most significant number of images, diagrams, and tables for succinctly summarizing information – something that I know students (and instructors) find valuable.
The first edition of this book was approximately 200 pages, and the second edition is nearly 300 pages, so a good amount of new or updated information has been added to the second edition. In addition to incorporating new references throughout, this edition has more illustrations, a chapter dedicated to common vestibular disorders, and a companion website from the publisher with 10 cases (including 17 videos to help support learning).
If someone in the field of Audiology was looking to add videonystagmography (VNG) or electronystagmography (ENG) to their clinical practice, this is one of the best books available to walk you through most of what you need to know for these vestibular assessments.
The only thing missing from my copy of this book is a signed message from the author (I had a nerdy fandom moment at an audiology conference where I met Dr. McCaslin and had my copy of the first edition with me, so naturally I could not resist asking him to sign it).
