some online photography books

i just stumbled upon this site. the arts section has some (old) photography books in html form. i figured people here might be interested in it. sorry, if it has already been posted.

Interesting that someone has taken the trouble to put these books in html form. You'd probably be hard pressed to find them or at least some of them any other way.

I can't recall this having been posted before. Thanks
