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 , 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.
