JF Ptak Science Books

I have been in business since 1985 selling uncommon, interesting, useful, and rare books in physics, math, technology, and social history. My store locations were in Alexandria, Virginia, and Georgetown, D.C., from 1985-2002. Note: we no longer ship overseas via first class USPS--all shipments must be made via UPS, FedEx, or DHL, or via USPS expedited (with door-to-door tracking capacity).
