Those who write, and from time to time, need someone with specific expertise to provide input on their area. Some of us have expertise in certain areas, and our input would be valuable to authors whose work dips into our corner of the world.
Whichever your camp, HARO may be for you. Simply go to http://helpareporter.com and complete the free registration.
Every weekday, I receive three mails from HARO (one in the morning, one in the afternoon, and one in the evening). Each e-mail gives a brief sentence summarizing what a particular author is looking for. Clicking on the link reveals more information. The list of links are grouped by general topic.
When I was writing Organization Made Easy!, I used HARO to gather input on several topics within the book. I received more information than I could use, and what I was able to use indeed added to the quality of the book. So, whether you are a writer or someone with particular knowledge and skills in your own corner of the world, HARO may be for you. Give it a try.
