One of the things editors look for in a pitch is publishing credits. A great way to get them is to submit your work to literary journals. Literary journals or literary magazines are periodicals devoted to publishing literature. There are many literary journals. Some focus on fiction, nonfiction, poetry, or all three. Some focus on concise nonfiction, flash fiction (a few hundred words or less), nano-fiction, and so on. The one thing that all the literary journals have in common is that they are looking for well-crafted material.
