Online Technical Writing: Free Online Textbook for Technical Writing

(View Complete Item Description)

This text came about in the mid-1980s while I was working at IBM–Austin, Texas, and teaching as an adjunct at Austin Community College. Using a desktop publishing system called Interleaf, I wrote this at a time when most students still used typewriters. There may still be vestiges of this era in these pages. In 1994, I discovered the web and began a mad dash through my lunch hours converting the Interleaf files to HTML using loads of macros I created in Emacs. In 2014, I began extensively overhauling this thing and trying to modernize it. Some of the examples are from my technical writing teaching days in the early 1980s at the University of Texas. They are dated but good examples. Readers are encouraged to send me updates!
