We live in a time of marketing. Without professional strategies and concepts for marketing, it is becoming increasingly difficult to reach customers and succeed in the market. This also applies to public libraries. On one hand, cities and municipalities lack the financial means to promote and maintain these traditional cultural institutions. On the other hand, competition in the cultural and educational market is greater than ever, with everyone vying for customers' favor. Public libraries today face the challenge of finding new ways to retain their existing clientele and attract new customer groups, thereby solidifying their significance as cultural institutions within the communities. In this book, readers will find ideas and recommendations on what a marketing concept for public libraries can look like and which strategies are sensible in today's context.
