Technical Note
Our microform publications are 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. Most of the material is in good condition. Some records comprise different types, thicknesses and colours of paper. Coupled with the variety of inks, pens or pencils used, this sometimes creates problems of clarity and contrast. Some items consist of carbon copies or comprise material on very thin paper, which has created problems of show-through, rendering the original documents difficult to read. Every effort has been made to minimise these difficulties and some openings are microfilmed more than once in an attempt to bring out all the features of the original. Nevertheless these original characteristics present difficulties of image and contrast which stringent tests and variations of density cannot entirely overcome.
The most responsible care has been exercised in the filming of this unique collection and every effort has been made to ensure that this microform publication meets the standards established by the Association for Information and Image Management (AIIM), the American National Standards Institute (ANSI) and prevailing European standards.
