The Cecil Papers is a major collection of early-modern historical documents from the reigns of Elizabethan I and James I/VI. More than 150,000 pages have been digitised in full colour to create a definitive online archive of almost 30,000 manuscript documents written by some of the most significant figures of Elizabethan and Jacobean history. These are accompanied by the complete Calendar of the Cecil Papers, featuring summaries and/or transcripts of many documents and two eighteenth-century volumes of selected transcriptions.
