Dylan Stableford rounds up the differing counts of magazine launches in 2007, as there at least three sources that track such information. For the record, the official source of all such information for this weblog is Mr. Magazine, as I’ve travelled to Oxford, Miss. (at least twice that I can recall) to visit the Mr. Magazine Launch-counting Laboratory. I know that if he and his staff of highly-trained magazine-counting professionals say there was a launch, there was a launch. No vaporzines counted, only magazines that make it off the press. His numbers are higher than the other sources because he does include magazines that may not be recurring. I’ve also observed that in recent years, Samir has done a great job of tracking custom-published magazines that don’t hit the radar of the other services that do such counts.
