Hi Gabriele,
The
PMBOK Guide is copyright protected by PMI. Please purchase a copy of your very own.
Linda is correct. There is a pdf download of the
PMBOK Guide and
Agile Practice Guide when you join PMI. The pdf copy is licensed to the PMI member and will have your name as the licensee at the bottom of each page. Your pdf is password protected, so you must enter a password each time you open it.
You also are unable to print from the licensed pdf and cannot copy and paste text from it either.
