I'm a songwriter and I've had some articles published in music trade publications, eventually, I hope to publish a book or two. I went back to school @ UCLA (English Degree) fortunately I can take short story, poetry, playwriting and screen writing classes, so I'm exploring. There are so many steps in the process. First, I would recommend taking a couple of workshops, depending on your area of focus (fiction...) and get some feedback. The publishing industry is suffering at the moment, but you may also consider self publishing down the line.
NOTE: Self publishing options through: Amazon, Scribd.com, and Lulu.com
Good luck!
