The most famous diarist in the English Language has a blog, it seems. Some industrious soul has been posting Samuel Pepys diary entry for each day on the web since 2003. Thus, today you can read what old Sam was up to on March 29th 1664.
Like every good blogger, Pepys has archives up, so you can also start from the beginning on January 1st, 1660. Pepys diary spanned the period from 1660 to 1669, and important one in English history since 1660 was the year in which the monarchy was restored.
Unless his faithful webservant gets tired, this blogger should be good for another five years worth of daily content.
