The decision makers at bookstores and libraries are incredibly busy people that get pitched numerous books each week. If you want to get their attention, you need to be fully prepared and buttoned up before you approach them. Book marketing expert and New Shelves Books Executive Director Keri-Rae Barnum suggests authors understand book sales terms, have your book's metadata on hand (such as the ISBN), and know the details of where and how your book can be purchased. Book buyers want to work with professionals that make their jobs as easy as possible. If you try to pitch a bookseller or librarian without this information and a copy of your book, you will likely be unsuccessful.
