The J. Allen Hynek Center for UFO Studies (CUFOS) hosts a collection of “Early UFO Periodicals.” Of key interest to Jim Moseley mavens, the first ten issues of Saucer News are included, then known as “NEXUS.” http://www.cufos.org/Nexus/
But wait, there’s more!
There’s also a collection of early issues of Gray Barker’s Saucerian: http://www.cufos.org/Saucerian/
