The Common Core Curriculum Standards point educators toward rigorous or deep learning so that students will become "college and career ready." College-ready students engage with text in thoughtful ways so that they arrive at insights through interpretation, discussion, and analysis. One reading anchor standard of relevance for school librarians comes under the heading "Integration of Knowledge and Ideas." The anchor standard calls for students at all grade levels to "Analyze how two or more texts address similar themes or topics in order to build knowledge or to compare the approaches the authors take." This anchor standard invites the school librarian to collaborate with teachers in developing and teaching sets of texts for students to read and compare. This is an opportunity for school librarians to apply their expertise and knowledge of literature--fiction and informational, print and digital. This article describes the meaning of "conceptual text sets," provides tips on how to select the best texts for text sets based on level of complexity and the Common Core Standards, and discusses the best way to teach text sets.
