Where would be a good place to find used/salvaged building supplies? ?

Question

What kind of a search would I do to find these kinds of places?

Answer 1

Yellow pages of the phone book.  In our area we have a Habitat for Humanity store, used building supplies, cheap!  

Answer 2

"Architectural Salvage".

Answer 3

Look for businesses that advertise they do remodeling, home improvements, etc.  When they strip out the area to improve it, most times they just throw the old materials away and a lot of them could be salvaged if you have the time.  

Right now across from my Mom's there is a garage full of boards, columns, etc. that could be reused for a lot of projects and the contractor is planning on stuffing them and the old garage into a dumpster and off to the landfill.
