Libraries and librarians are indispensable to student learning and the formation of researchers at the doctoral level. This book identifies five areas and sixteen principles that need to be considered by theological schools when optimizing library operations to serve doctoral programs. As an illustration of these principles, the book provides narratives from four theological libraries - in Nairobi, Hong Kong, Bangalore, and Amsterdam - that have successfully transitioned to serve doctoral programs. The contributors present tested best practice alongside their successful experiences pioneering libraries that serve doctoral programs in challenging situations. An invaluable training resource for Majority World librarians, this book also offers insight into quality guidelines for accreditation agencies supporting theological institutions in developing robust and flourishing programs.
