We have been in business since 1985--including a store in Georgetown, D.C. from 1985-2002--specializing in significant and hard-to-find works in modern (say, after 1850) physics, math, astronomy, and technology, and other bits and bobs. Shipping notice for overseas parcels: customs, VAT, and all other shipping fees and add-ons are the responsibility of the buyer.
