With the proliferation of inexpensive "pay-for-publication" options, this has become a confusing question. Many writers believe that "self-publication" refers to any mechanism by which the writer bears the cost of publication -- including subsidy electronic and print-on-demand publications. Many vendors encourage this belief, as "self-publishing" tends to sound more respectable than "subsidy publishing." As a traditionalist, however, I intend to stick to long-accepted distinctions between self-publishing vs. subsidy publishing. The self-published author is responsible for a much greater range of tasks (and expenses) than a subsidy-published author -- and it is these additional tasks and challenges that will be addressed in this section (though subsidy-published authors will find much of value here as well).
