Edward R. Hamilton Booksellers deals mostly in overstock and remainders. Wide selection, but it seems to be whatever they have at the moment; I’ve never tried to get a particular book that I didn’t see in their catalog. Good prices and flat $4.00 shipping for any size order.
Hamilton is an old school remainder dealer. They had a great mail order catalog in the pre internet days. I remember buying the WW2 ace pilot Joe Foss’ autobiography there for $3 new. Happy days.
I have purchased many books from Hamiltons.
Wonderful stuff. Greatly expanded my horizons.
