Old series newsletters ran from 1959 to 1975. Digitised copies up to 1965 are available here. Numbers 1:26 (1965) through to the start of the new series (1975) have not been digitised yet.
The new series started in October 1975. Older issues are scanned typed documents. In more recent times online newsletters are better quality, converted directly from digital (e.g. Word-processor) format. Where available, recent online newsletters use colour photos (the print newsletter is monochrome).

Most computers are shipped with software to view PDF format files. Depending on local settings the files may open automatically, otherwise they will be downloaded and you will need to explicitly open them with a PDF viewer.
