1. Find the document you want,by entering a search word in the box to the left of this pane, or searching in the "Categories" box,  or by just scrolling down and clicking through pages until you find its title. 
Documents will generally be one of four types, indicated by a suffix after their name:
PDF  means "Portable Document Format" - this gives you a "photocopy" of the original document, pictures and all, but you can't easily make any changes to it yourself. To view it, you will need to have a program called "Adobe Acrobat Reader". If you haven't already got it, it can be downloaded for free from Adobe's website here. 
WORD means it can be viewed and edited in Microsoft Word, which is the most widely-used Word Processing program. If you haven't got it, either download the free Word Viewer (which enables you to read Word documents but not edit them) or ask us to send you what you want as an "RTF" document, which can be opened by any computer.
JPG means that it is a photographic or visual image, and this can be viewed by most computers. 
PPT means that it is a Microsoft PowerPoint presentation - the "slides" used at meetings. You would need to have PowerPoint installed on your computer, or to download the free PowerPoint view-only program, to open and see these. WARNING: these are likely to be quite large files (see below). 
Check the file size (first line of the info box). If it is more than 500K, be aware that it might take quite some time to download if you have a slow (non-broadband) dial-up internet connection. This particularly applies to the PowerPoint files which can be over 1Mb and would take a long while.  You can ask for them to be posted to you on a CD if that is easier. Broadband users should be okay.
