Looking to publish in any form, and get paid, not just on-line.
I suggest taking a look at the book Writer’s Market, or (what I use), their website found at www.writersmarket.com. I also suggest a book by the same company called Formatting & Submitting Your Manuscript for help with the technical aspect of what a submission should contain. It is a very valuable resource to find outlets that may be suitable for the kind of story that you have written.
You have to do your research as well. Gather some names of magazines, journals, websites, etc and then take a look at them! Don’t just read their submission guidelines but take a look at what kinds of stories they contain. Spend time at your local public library, they normally have a vast collection of magazines that can help you do this research. Honestly, you are probably much too late for most magazines for this Christmas, but you could start to do some research for next year.
And you will get rejected. Possibly quite a bit. It has happened to every great writer (and musician, artist, etc). Have patience and keep submitting to appropriate publications, and your stories will find homes!
I know it can seem impossible, but new writers DO get short stories published by reputable magazines and journals. One gentleman in a writer’s group I frequent just had his first acceptance to a great magazine. He won’t be retiring on the check, but it was a little extra cash and a big victory.
