If you are interested in the history of the 911 I can highly recommend the book titled "Porsche 911x911" 3rd edition by Porsche Museum. It has 911+ pages mostly filled with beautiful photos and some additional information. Here are some pages to give you an idea. The book is available on Amazon
Size of the book; can't show the weight, but it's on the very heavy side.
TOC; all texts in the book are in the shown languages
didn't know that the wheel design of 4tracs new Turbo dates back to 1966
Uncommon use of a 911. Maybe a new option for the 992 :)
If you didn't know why it's called 911
Last but not least, I just love the old ads
