For me it has been showing up at libraries and asking them to add my book to their collection. I get pretty good levels of interest, and I am no longer just a paragraph in some catalog. To my surprise libraries then ask me to do an author presentation rather frequently. I do have a structured approach that I worked out. I leave a 3" x 5" card with all of the order information on one side (plus my Kirkus one sentence), the other side has a summary of who the book is for/what the story is about.
