People Working with Found Footage,
Find here attached my master Thesis on Politics of 'Found Footage' made at the University of Lausanne, UNIL, Switzerland. It's all in french....
You will find inside, a largely documented historiography of found footage as genre, approaches on theory of found footage (William Wees, Nicole Brenez, Yann Beauvais & Peter Tscherkassky among some comptemporary philosophy.)
You can find also film critics on Ken Jacobs' Star Spangled to death, Abigail Child's The Present is behin you and, last but not least, Craig Baldwin's Sonic Outlaws.
