Artmark is a blog by the painter Mark Warren where he shows his work and comments on various art and cultural matters in a very subjective manner. He loves to show underappreciated artists and some rather bizarre historical images. He does not like Andy Warhol! http://artwarren.blogspot.com/

Two of the greatest used bookstores in the valley share one space in Hadley, MA. They are the newly moved TROUBADOUR BOOKS and GREY MATTER BOOKS both at 47 East St. Call 413-387-0160for more info. I am posting this now because the two stores are sharing a big 35% off sale this Thursday, March 31, through Sunday, April 3, 2011. They have great Art Book selections and a huge inventory of poetry, philosophy, literature and on and on.
