The iPhone users manual arrived today. It is well constructed and has quality paper. The books are 5 x 7. I assumed that they would be 8 1/2 x 11 so that the print would be large enough to read. Your statement says that an index is included. There is a Table of Contents at the front of the book but there is no index, An index that lists subject mater alphabetically and the page number where it can be found is indispensable. Without an index, locating a subject matter becomes extremely difficult and time consuming. In one of our classes in school, the professor held up two books. He explained that the first one had an index; the second one did not. He threw the second book in the wastebasket. Without an index to quickly locate material, the book will never be used. For example, 0n page 17, the book discusses “Dark Mode”. It discusses what Dark Mode is but not how to turn it on or where to find it in the book. On page 53 it describes how to turn Dark Mode on or off. But, Dark Mode is not mentioned in the “Table of Contents” nor in the nonexistent Index. The book is not user friendly and is definitely in need of improvement. It needs an index. If an index is available, can it be supplied.? Rich and Sandy Brown 1301 Oakleigh Rd. N.W.
