Videri is a wiki about history and historiography. It consists of summaries of historical and theoretical works, along with interpretive essays that provide overviews of important issues in history. It also includes an Orals Survival Guide to help graduate students prepare for their exams. There is already some great content on Videri, and we hope that readers will contribute their own their notes and essays to the site for the benefit of the public at large.
