For somehting like the TAT throttle articles that were published almost 50 years ago, copyright isn't so much of an issure but something from last year's issue will be. Even with the older issues, there can be copyright issures if the info is put out to one and all. Best thing is to not bother but rather let others know of the issues of interest and let htem find the issue. Many clubs keep old issues and there are allways issues for sale at swapmeets.
