Amateur magazine publishing as a hobby dates back to the late 19th century. H.P. Lovecraft, Ray Bradbury, Harlan Ellison, and many other luminaries in science fiction and fantasy spent many hours at the mimeograph machine creating work with surprising durability. Michael Dobson's Random Jottings has been published for nearly 50 years (not counting a small 34-year interruption), and in its modern incarnation has experimented with special issues and modern print-on-demand techniques. All are available as free PDFs; some issues are also available in printed form.
