Do not forget your local public library! Talk to the librarian about their acquisition process and how you can enhance your visibility (RWA "Romance Sells" catalogue, for one). Know how you and your librarian can work together to your mutual benefit. Can you hold a reading or panel discussion there? Offer a workshop? Getting readers to the library helps them, and when they stock your books it helps you!
Librarians have ferociously embraced the digital revolution as well and are generating apps that can allow you to download to your e-reader books via the library system.
Libraries have been helping us learn, read and enjoy books all of our lives. Now with funding issues they are struggling for theirs.
Support your local library (and librarians!)!
