Resources

In my study of important typewriters from the 1870s to the 1970s I have relied heavily on a number of important reference books.

Here's a list of the ones I have found most helpful:

• American Typewriters, A Collector’s Encyclopedia by Paul Lippman, 1991

• Antique Typewriters & Office Collectibles by Darryl Rehr, Collector Books, 1997

• Antique Typewriters from Creed to QWERTY by Michael Adler, Schiffer Publishing, 1997

• The Typewriter Revolution, A Typist’s Companion for the 21st Century by Richard Polt, Countryman Press, 2015

• Typewriters, Iconic Machines from the Golden age of Mechanical Writing by Anthony Casello, Chrionicle Books, 2017

I have also found these websites very valuable:
