I have written a monograph on Kähler groups. Here is a preliminary version. The text still contains mistakes and misprints. I will polish it in the coming months.

Comments are welcome!
Thanks to Benoît Claudon, Sam Hughes, Yuan Liu, Claudio Llosa Isenrich and Mohan Ramachandran for comments on some pre-preliminary versions and to Thomas Delzant for many hours of discussion on the topic of Kähler groups.
