Last chance to get in on my April online course! It’s an easy, affordable way to learn directly from a qualified historian (Ph.D., Columbia University) how to think and reason about history and investigate historical claims. You also get to ask me any questions about the subject you want for a whole month, and get my full attention in reply! Register now. For more info, see Thinking Like a Historian: Historical Methods, Practice and Theory. (Requires a print or electronic copy of Proving History.)
