It's apparently still going 75 years later, now published by Wiley. It's odd then, that a PR firm should have set up a blog with the same name, Architectural Graphics Standards.
Its ambition is apparently that of 'collecting, analyzing, and presenting news stories related architectural graphics and their uses.' On the other hand the stories currently to be seen on the site are about such things as Green issues, BIM and a couple of buildings. In short not so much graphics standards as the sort of sundry things you get on any low key architectural blog.
Maybe it's my natural suspicion about the involvement of PR flacks in anything to do with our cozy little world but you want to ask the question about ripping off that hallowed 75-year old title. And why do PRs want to run an architectural website anyway?
