With the use of social media in learning by learning professionals still relatively young, there are only a handful of books written on the subject. To be honest, several of them overlap somewhat in the content provided, leaving me to ask after reading the third one in the span of a month "Do I really need another book to tell me what a wiki or a blog is about?" My answer to that is a resounding "No!" It is, therefore, with pleasure that I recommend to you Jane Hart's Social Learning Handbook (©2011, Centre for Learning & Performance Technologies).
