Purpose -Strategic plans are developed and executed by businesses in order to chart a course toward an idealized future destination for the organization. Normally, this means aspiring to become an industry leader or niche holder by increasing market share, developing customer loyalty, penetrating new markets or some other defined goal that is ultimately premised on growth in revenue attainment. Because of the competitive nature of business and the environmental changes that have occurred and continue to occur at an increasing rate, marketing has become a key functional area within most enterprises' strategic plans. Today's strategies require the development of plans that embrace customer engagement in an effort to increase revenue. As such, marketing is fast becoming a critical functional area surrounding the development and execution of a strategic plan. Examining marketing's role in strategic planning, as well as the critical thought work conducted by marketing and sales personnel as they influence organizational cultures that are friendly to implementing competitive strategy and planning activities, is useful for libraries if they wish to engage in beneficial and viable strategic planning of their own.

Findings -The paper finds that libraries that engage in strategic planning can incrementally improve their chances of success during the execution of that plan if they make an effort to include the marketing process throughout the development and execution of such plans. Additionally, since marketing and its implied customer orientations provide a strong conduit to an organization's understanding of customer needs and perceptions of value, library strategic planning that incorporates traditional marketing elements and tactics like environmental scans, customer value creation and promotion of unique benefits will provide the best foundation for competitive library strategic plans. Practical implications -The authors rely on their practical and theoretical experience in marketing and planning to convey a more purposeful sense of library strategic planning that ...
