The Historian's Toolbox introduces students to the theory, craft, and methods of history and equips them with a series of tools to research and understand the past. Written in an engaging and entertaining style, and filled with fascinating examples, this best-selling "how to" book opens up an exciting world behind historical research and writing. This fourth edition expands the repertory of tools and techniques available to students entering the workshop of history. These include materials on the Kennedy assassination, the litigation of Van Gogh's Night Café, local town histories, contemporary history, Twitter, and the contemplation of the end of history as well as the Sixth Extinction in a new epilogue. The book demonstrates the relevance and expanding possibilities of the study of history in our cacophonous information age of tweetstorms and fake news; it emphasises the increasing value of critical thinking, facts and evidence in the face of political lies and conspiracy theories. Material added to the fourth edition will resonate with a new generation of computer-literate readers in the face of climate change. The Historian's Toolbox continues to be a seminal text for supporting students throughout their study of history and an accessible teaching tool for instructors.
