Invention & Technology Magazine is a quarterly magazine dedicated to the history of technology. It is a spinoff of American Heritage magazine. It started in the summer of 1985 and printed three issues a year until 1992 when it became quarterly. With the Summer 2007 issue (vol 23 No. 1), publication was suspended (along with American Heritage)[1]; however, a Summer 2008 issue (vol 23 No. 2) has now been published.[2].
