Calendars provide summaries full enough, for most purposes, to replace the original documents. These summaries are printed in chronological order and do not necessarily reflect the archival ordering of the documents (hence ‘calendar’). They are the primary finding aid for the records that they describe. This series details cases heard in the Court of Common Pleas in the City of London for the period 1323-1412. The court dealt with cases between citizens which did not involve the king or queen.
