Academic librarians working in instruction are at the crux of professional, higher educational, and societal change. While they work with disciplinary faculty to ensure learners are critical information consumers and producers in 21st century ways, how do academic librarians develop a sense of their own identities as post-secondary instructors? Using both broad and in-depth data from practicing instruction librarians, this book identifies the catalysts and influences in academic librarians' perspective development process. From these factors, then, instruction librarians and librarians-to-be can hone their own instructional identities and transform their teaching practices. This focus on understanding this perspective transformation process around instructional identities offers both working academic librarians and LIS graduate students an innovative way to think about their roles as educators. While many books explore the practical or how-to aspects of teaching in libraries, Transforming Academic Librarianship: How to Hone Your Instructional Identity and Adopt Best Teaching Practice takes a step up and examines how academic librarians think about or approach instruction as a part of their work. Through explicating this metacognitive process, this book helps both academic librarians and librarians-to-be to more intentionally consider their teaching practices and professional identities.
