| Domesday Book | Sometimes called just Domesday, it is a written record of a survey of England ordered by William the Conqueror in 1066. William was an attempting to register the landed wealth of the country in a systematic fashion and to determine the revenues due him. The survey was executed by groups of officers called legati, who visited each county and conducted a public inquiry. The set of questions that these officers asked of the town and county representatives constituted the Inquisitio Eliensis; the answers supplied the information from which the Domesday Book was compiled. Domesday is a corruption of Doomsday (the day of the final judgment); the work was so named because its judgments in terms of levies and assessments were irrevocable. The original manuscript was made in two volumes. The first and larger one, sometimes called the Great Domesday, included information on all England, with the exception of three eastern counties (Essex, Suffolk, and Norfolk), several northern counties, London, and some other towns. The surveys of the three eastern counties made up the second volume, which was known as the Little Domesday. These documents were frequently used in the medieval law courts, and in their published form they are occasionally used today in cases involving questions of topography or genealogy. | Colonial Diseases |

| double date | A double date appears on some documents as a result of two changes introduced by the adoption of the Gregorian calendar, introduced by Pope Gregory XIII in 1582 to resolve the error caused by the Julian calendar in use up to that time. Scientists resolved that a year was slightly longer than the 365 ¼ specified by the Julian calendar, which resulted in the loss of 10 days. The new calendar also changed the first day of the year from March 25th on the Julian calendar to January 1st. Different countries adopted the new calendar at different times and the practice of providing a double date was common. The British Commonwealth and the United States adopted the new calendar in 1752. By this time, the calendar was behind by 11 days. So, the day following September 2, 1752 was decreed to be September 14, 1752.. | Colonial Diseases |
