Rebecca Langley lays out a specific list of to-do tasks to try and get your book into libraries. It’s not for the marketing faint of heart, but if you can get in, libraries are all over this country.
Getting into your local library is probably easier than what she describes. Knowing your librarians and finding out what they might be looking for for their patrons is helpful. Just ask. Rebecca is right, it’s all about getting patrons in the door.
She doesn’t mention audio books. Having your book as an audio book is also another plus. Findaway voices is a new service that puts your audio book on multiple formats (including audible).
And look at that list of reviewers (Library Journal, Kirkus, PW, Booklist…) early in your writing process. Many free reviews require the book 3 months before publication. You can send them an ARC (advanced reader copy), so that is helpful. But you’ll have to plan ahead. I know once your book is done, you really want to get it out, but getting your book reviewed by a few of these companies can go a long way in selling more books. I know I wish I had done this for a couple of my books.
And speaking of reviews, you’ll want a decent number (10-20+?) of reviews on Amazon before you do any marketing. Librarians look at Amazon too.
Best of luck!
Library books have a longer shelf life than in bookstores, and they get more action, because there’s no financial risk for the inquisitive reader.
