While publishing is possible with the large publishing houses, it is extremely hard to have your material get to the point where it is seen by the proper channels. Instead today many people are opting to self publish first, then if they are successful, they have something they can bring to a publishing house to show that there a audience for your material.
Over the next couple of weeks I will be putting out podcast’s that show give a path to have your material published, no matter what type of material you are writing. Even though poetry will take a different path than fiction, many of the paths are the same for both. Since I have had poetry published with groupings with other poets, but also had a book published by itself.
