Tools of communication have transformed American society time and again over the past two centuries. The Museum has preserved many instruments of these changes, from printing presses to personal digital assistants.
The collections include hundreds of artifacts from the printing trade and related fields, including papermaking equipment, wood and metal type collections, bookbinding tools, and typesetting machines. Benjamin Franklin is said to have used one of the printing presses in the collection in 1726.
More than 7,000 objects chart the evolution of electronic communications, including the original telegraph of Samuel Morse and Alexander Graham Bell's early telephones. Radios, televisions, tape recorders, and the tools of the computer age are part of the collections, along with wireless phones and a satellite tracking system.

- Description (Brief)
- This patent model demonstrates an invention for a flatbed cylinder printing press which was granted patent number 172974. On a cylinder press, a strain was put on the press each time the bed stopped at the end of its tracks while the cylinder continued to turn with its original momentum. This patent dealt with the problem by braking the cylinder at the same time as the bed. Calvert Cottrell (born 1821), press builder, formed a partnership with Nathan Babcock that lasted from 1855 until 1880. He then set up a company with his three sons, C. B. Cottrell & Sons. Cottrell was responsible for several important improvements to the flatbed cylinder press.
