This article examines the association among inquiry, the Common Core State Standards (CCSS) and school librarians. It explains the significance of asking questions, and describes the characteristics of the questions that are central to inquiry learning. The role of school librarians in inquiry learning and the implementation of CCSS is also discussed. It notes particularly that, looking at the CCSS Anchor Standards, the skills necessary to address questions--citing, analyzing, interpreting, assessing, integrating, supporting, producing, researching, gathering, integrating, and evaluating--are librarian skills. Expertise in these questioning skills helps librarians support their colleagues in their teaching endeavors.
