Here are some ways that I think work really well to market a library's fiction collection:
1: Displays-I don't think we can underestimate the power of a good display. My library has a display that is right by the main circulation desk. This display reminds me of the strategically placed candy shelves that line the checkout aisle and the grocery store. Both do an excellent job of making a person grab just one more thing before they leave.
2: Book Clubs- I think book clubs are a great way to market a library's fiction collection and grow new readers, especially book clubs that meet away from the library at breweries or coffee shops. Book clubs that have some special hook are effective at grabbing people's interest and can be unique to each library. For example, at my library the adult services staff are going to start a new book club called "Souper Readers" or something similar. Anyway, the idea is that at each book club meeting they will have some soup to snack on while they chat about the chosen book.
3: Book toks or Short Videos-I think we've all seen the power that tik tok booktok videos have had in bringing attention to books that were getting musty on library shelves, Colleen Hoover anyone? This isn't something my library currently does, but I do think its a great way to promote books and highlight titles in a library's collection. It's also a great way for library staff to share some of their favorites and connect with the library community.
