Getting Interviews By Establishing Yourself as an Authority

There is something about being a published author that immediately establishes some level of credibility in a conversation. And rightfully so. Writing a book is hard work. As I've stated before, national statistics indicate that 82% of the population believe they have a book within them to be written, but only 8% will ever sit down and really make it happen.
For those in the 8% category...congratulations. Hopefully the reason you wrote your book is that you have some level of experience and knowledge on your subject that was important to impart to others. Hopefully new, insightful knowledge. So how can you parlay that into media coverage?
Ever wonder how people get called and then chosen as the "authority" for newspaper articles or television and radio interviews? Journalists are always looking for quality content and quotes they can use from solid sources in their articles. It's the nature of the beast in their world. Good journalists work to use at least three sources or more to support their point of a story. So how can you be one of their sources?
First, determine your levels of expertise. What are topics in which you can truly and significantly contribute?
Second, write short articles in these expert areas of information and offer them to an online e-zine source who will then publish your article. This will increase your digital footprint in this area.
Third, you can sign up on HARO (Help A Reporter Out). It's free. It's simple. Here is how it works:
You will receive three emails a day, Monday through Friday at 5:35 a.m., 12:35 p.m. and 5:35 p.m. EST, with queries from reporters and media outlets worldwide. Scan the emails, and if you're knowledgeable about any of the topics, answer the reporter directly through the anonymous email address provided at the beginning of the query.   
(NOTE: Be sure to read their "Rules" page so you are familiar with their expectations.)
As you make yourself available as a "source" and can provide that quality content, journalists will make note of you and call you back if they are writing again on that topic. It makes their job easier to have sources they can depend on.
But remember, they run on tight schedules. If they contact you, get back with them immediately. I've had authors, in which I have secured interviews for them with high profile outlets, that were subsequently lost because the author chose to do something on their "to do" list before contacting the reporter. When the did call the reporter back, the story had been written or another expert secured. Don't lose your opportunity by delaying! Call them back immediately.
Provide what they need. If you can't, be honest. Don't fake it.
And be sure to watch for those emails. As you are proactive to get your name out, eventually calls will come.
