I won't lie: I know NOTHING about the business of getting published.
This weblog focuses on the writing craft, not on what happens once you're finished with your story or novel.
But: You are probably going to try and get published For Real (and no, vanity publishing doesn't count). What can I tell you? Only this:
1. You're going to enter a World of Pain...
2. Listen to the advice of people with actual experience, like Neil Gaiman...
3. Consult the Preditors and Editors index to find a trustworthy agent.
Good luck, and... don't send money to agents or publishers. Ever.
