About Kuenzig Books

Based in Topsfield, Massachusetts, Kuenzig Books buys and sells rare and/or interesting items in many fields with a focus on 19th and 20th century Science, Technology, and Engineering. We are particularly interested in the History of Computing, and the speed with which the technological innovations of the 20th century have impacted the way we live. You'll discover some depth in Physics, Mathematics, Nobel Prize authors, Medicine, Scientific Instruments, and Chemistry.

We continue to deal in scientific artifacts (microscopes, philosophical apparatus, early motors, early computers, calculators, slide rules, etc) and you'll find them mixed in with our books at tradeshows. Please inquire if you are interested in artifacts as few are listed on our website.

We also buy and sell ephemera, photography, manuscript material, diaries, letter archives, and business archives in any field. If it tells a strong story, we're interested.

Our History

Kuenzig Books was founded in 1996 by John F. Kuenzig who earned his Computer Science and Electrical Engineering degree from MIT (the Massachusetts Institute of Technology). Mr. Kuenzig has a patent in speech recognition and was co-founder with Steve Gladstone of Hammer Technology (which built test equipment for the telecommunications industry). John enjoys hiking, tinkering with well made mechanical devices, and science fiction movies.

Our Services

While we do not have an open shop, visitors are welcome by appointment. We are located 40 minutes north of Boston. We exhibit at Northeast book fairs including the Boston ABAA fair.  We strive to bring some of our newest acquisitions to bookfairs, and typically place them first on our website for existing customers to review.

We have worked with multiple institutions and major private collectors. We can assist with buying, searches, downsizing and collection development. 

We're now mobile responsive.  And now you can sign up for topic notifications to hear monthly about new arrivals in your interest area(s).  Join our separate e-list to hear about sales, trade show announcements, and new catalogs.  We appreciate your past (and future) business!
