One way to get the word out there about your books is to contact local media.
By that I mean, local newspapers and magazines. The ones that are freebies at your hometown market are read by locals. I recently was able to get a by-line in a Long Island Magazine, Long Island 50 Plus LIFESTYES . My column is called the Writers Corner. I have added a link. The column is on page 11. Although my column is usually about other authors, my name appears. When I writer about a local author event, my website appears.
Get to know your editors and reporters from your local papers. You might even ask the reporter if you can shadow them at am author event.
