A new acquisition in the library is Teaching History in the Digital Age by T. Mills Kelly. The book will soon be available in the new books area of the Moffitt Library Lobby [D16.255.C65 K45 2013], but is also available in a free Creative Commons licensed web version.
The book is marketed as a guide for practitioners, but I encourage students to take a look at it, especially the chapters on finding sources and evaluating them. Kelly does an excellent job of articulating how radically the universe of available resources has expanded within the last twenty years and how that offers both opportunities and challenges to students of history.
For more information, see Lincoln Mullen’s recent review of the book in The Chronicle of Higher Education.
