If any of you have the opportunity or need to write corrections to articles appearing in magazines like AudioXpress, NutsN'Volts, EDN etc. please add a post-script asking the editor to "memorialize" corrections by placing them (the corrections) on their website. As an avid reader and subscriber for almost 40 years, I am now practiced in reviewing subsequent issues before undertaking any project. How much easier this would be if the corrections and amplifications could be sourced from the publisher's website.
