This book discusses how librarians have become accidental teachers in the academic university setting. It covers how (if at all) librarians are prepared by MILS programs to teach, compares typical characteristics of teachers versus librarians, and presents tactics on how to learn effective teaching skills on the job. In addition, readers will learn about the history of library instruction, the different types of library instruction, and the dynamics of one-shot library instruction, classroom culture, faculty buy-in, and collaboration.
