There is a ton of useful information packed into this little book.
From the back cover -
"This book is intended as a beginner's guide to the Commodore 64. In it, we will be giving you masses of useful information and programming tips as well as describing how to get the best from the powerful sound and graphics facilities. The only assumption we have made is that you already have a copy of the Commodore 64 User's Manual(which comes free with the computer anyway!)"
