This document summarizes a presentation about library design for 21st century learners. It discusses trends showing how student technology use and learning styles are changing. This impacts the need for new types of library spaces that are flexible, collaborative, and integrate technology. The presentation provides a case study of how one high school library was renovated by gathering input from students and staff and reconfiguring the space to improve visibility, access to natural light, and allow different types of quiet and active learning areas. The goal is for the library to serve as a learning commons that supports different modalities of independent and group work in a flexible, technology-rich environment.
