Some material on the SPUC website is in portable document format (PDF).
This allows the appearance of files which have been generated in
software such as Word and printers' page-layout programs to be retained
when they are placed on the web.
PDF files tend to be larger than web pages and therefore take longer to
download.
To
view such files you need software such as Adobe® Reader® which can be
downloaded free of charge.
If you use Adobe Reader to look at PDF files, you can search for
entries with that software's search-facility which is accessed by
clicking on the button that has a picture of a pair of binoculars on
it.
