A Workbook is a study companion, may contain key Power Point Slides used in a study, with an area for you to take notes (see pictured below of our Commentary Workbook - left).
A Handbook is the study notes of a particular study (sometimes referred to as Supplemental Notes, PDF Study Notes or PDF Notes). Handbooks come in either Printed Paperback, or digital PDF downloadable file formats (see pictured below - right).
Handbooks often come free on a CD with our studies in PDF format (such as Commentaries and Topical Studies). However, we found many people like the option of purchasing the Printed versions of these notes. You may also print the PDF notes for your own use, however be aware that some may consist of several hundred pages.
