I have seen other authors (Miranda July for ex.) publish short stories in literary magazines and these short stories were part of published novels. I was guessing the short stories came before the novel. ? I was wondering whether it would be a good idea to submit a chapter of my manuscript to a literary magazine. Publishers generally want exclusive rights to the work, right? But would most publishers mind if an excerpt were previously published in a magazine? Would all? I thought maybe some authors published a piece of their novels in magazines beforehand to gain a reputation/prestige before getting picked up by a publisher. But if that's not the case, I don't want to toss my novel in the trash by only getting a piece of it into a magazine. Advise. Plz & thx.
