Terry Anderson has released the second edition of his popular Theory and Practice of Online Learning ( direct link to entire book in .pdf ). The book is available for purchase or as a free download. Topics include social media, philosophies of technology, mobile learning, cost decisions about technology, libraries, learner support and more. On a personal note, I appreciated Mohamed Ally's opening chapter on learning theory, including extensive discussion on connectivism. The broad range of subjects, both theoretical and practical, ensures that this publication will continue to be a critical resource for trainers, educators, and students.
