Hanover Historical Texts Project is a collection of primary source texts from ancient times to the modern era in English translation. There is a great number of interesting texts, for instance accounts of Zeno, he of the paradoxes, the diary of Lady Sarashina, a lady-in-waiting in Heian era Japan, a letter from Count Stephen of Blois and Chartres, a crusader writing to his wife, Arthur Young's travels in France before and during the Revolution, a report by the American ambassador in St. Petersburg on March 20th, 1917, immediately after the February Revolution, and finally Petrarch's letter about his graphomania. That last one is from what is perhaps my favorite part of the website, a trove of Petrarch's Familiar Letters. But there's much more in the Hanover Historical Texts Projects besides what I've mentioned.
Mapping Petersburg "..explores the everyday life and the material, political, and literary culture of St. Petersburg [..] at the beginning of the twentieth century. It maps eleven itineraries through the city with the purpose of creating a palpable sense of life in Russia's late imperial capital on the eve of the 1917 revolution and during the subsequent decade."
