A really great idea for a reoccuring book display is what I call #FiveForFriday. It involves simply taking 5 books on any theme that comes to mind and promoting them in your building, on your social media, and anywhere else you promote your library. This is something that can be rotated among your staff so that everyone can participate. You will also have the chance to promote parts of your collection that the staff who regularly put up displays might not have considered.
One example is from the image below. Titan Books promoted some of their horror authors as retweeted by Gabino Iglesias. It's a simple picture of a ghost holding a stack of books. Create a digital display in your eBook platform, a web page with links to your catalog, and/or a book display in your building that includes these titles.
Create a calendar at least several months out in advance and allow your library staff to sign up for a Friday. You can create a form where staff can list their theme and the five titles that they wish to promote. Of course, staff should be aware that a library need may preempt their post, pushing the list forward.
Create guidelines for staff requiring that their five books be backlist titles and not current bestsellers, the authors are not regularly on the bestseller lists, there are diverse authors included, and as much as possible books are not repeated.
Since we are in October, this week's suggestion is vampire novels. Vampires are back but they are terrifying and brutal. Authors such as Stephen Graham Jones, Hailey Piper, and Andy Davidson have upcoming vampire novels which would also allow you to promote the idea of putting holds on upcoming books. Never assume that your patrons know everything about your library.
There are likely many options in your collection for staff to select including movies. The pick for this week is vampire novels by women writers. I have picked five suggestions below but use what is in your collection!
