Maker learning spaces in schools and public libraries are made real through the narratives of professional librarians around the world, comprising the collaborative activities, experiences, and perspectives of librarians as they have implemented makerspaces for students of all ages. School Library Makerspaces in Action is for any librarian looking for inspiration for their own makerspaces, hackerspaces, fablabs, or DIY locations and how to use these spaces in libraries and educational settings. Contributions from authors around the world address the needs of most all readers, including how to provide the staff training necessary for a successful makerspace. Each chapter is written from an author's personal experience, and with only a little fine-tuning and imagination, many of these ideas can be used throughout all levels, disciplines, and subjects in K–12 education and carry over into higher education. The successes and optimism shared in this collection will inspire librarians and educators to think positively about how to implement maker learning locations, train staff, and use makerspaces in their libraries and classrooms to promote and share new ideas.
