Marketing involves creating value for customers through communication and relationships. It is about delivering the right content to audiences, not just advertising. As the number of internet and social media users grows, marketers must shift from mass marketing to targeted strategies using platforms like social networks, blogs, microblogs, video and photo sharing to engage audiences. Libraries can increase their visibility and promote programs by creating profiles on these platforms to connect with communities without requiring real-time interactions. Building networks and partnerships allows equal access and helps libraries remain visible in their role of serving communities.
