In reading Purcell's writings, whether in manuscript or publication, there are many references to important texts that are now very difficult to obtain. These pages accumulate those materials as PDF files as they become available. The downloads have been broken down into chapters, or groups of chapters, to keep file size manageable. Some of the files are in TIFF format. Also, new technologies are making available materials
