This book explores how marketing strategies - used in businesses and organizations - can be applied to promote libraries by placing users at the heart of every decision. It positions the library within a rich and diverse cultural ecosystem that includes bookstores, publishers, professional associations, magazines, and museums. In today's landscape, the user experience (UX), once exclusive to retail and digital industries, is now a shared priority across these sectors, and a key component of modern library marketing. From audience research and satisfaction surveys to loyalty-building strategies, cutting-edge digital tools, and the rise of AI-driven practices, the book examines the evolving face of library marketing. Drawing on insights from experts across Europe (notably the Netherlands) and the French-speaking world (Canada, France, Belgium and Switzerland), it offers a comprehensive and forward-thinking look at the new challenges and opportunities shaping the profession today.
