Most books will repeat information on a subject when they are syntopic like computer books. So your approach to handling these would be similar to a syntopic reading. You have a central purpose what you want to learn from these books. Then you PhotoRead the lot. Do a brief activation and decide which book resonates most for you for your current purpose. Activate that one.
Your next learning might be more activation on another book. If you are self learning without a course curriculum consider grabbing a book like How to in 24 hours. They will set the stage for a step by step learning however you can turn to the other books for background information or even activation if there is another book that explains it better or in a way more interesting to you.
