Our microfilm publications have been prepared and produced in accordance with recommended and established guide-lines for the production of microform of superior quality. These conform to the recommendations of the standard guides to good microforming and micropublishing practice.
Attention should be drawn to the nature of the original material. A few manuscript documents consist of faintly legible correspondence and records written with a variety of inks, pens or pencils and on paper of many different types and thicknesses. A few items are stained or discoloured at the edges, or comprise material on very thin paper, which is so thin that there is show through that renders the original document difficult to read. Some items consist of carbon copies of documents and these again pose problems where the original is very faint or blurred.
These original characteristics present difficulties of image and contrast which stringent tests and camera alterations cannot entirely overcome. Every effort has been made to minimise these difficulties. Subject headings and item numbers are clearly marked. Each frame is filmed with a vertical strip target which identifies the relevant Public Record Office piece number in Class FO 371.
The Public Record Office at Kew, England, has exercised the most responsible care in the filming of this unique collection and this microfilm publication meets the standards established by the Association for Information and Image Management (AIIM) and the American National Standards Institute (ANSI).
