The home page presents a collapsible menu on the left hand side. Clicking on a particular item in the menu enables you to "drill down" even further, into a second level, and if relevant, a third level category of related pages and information.  The main navigation is browser friendly and is not dependent on client side javascript.

Top and bottom level navigation - links

At the top and bottom of every page there are a number of links to assist with navigation and assistance with this site.

Publications on the PTG website

What is a PDF file?

A PDF file is a self-contained cross-platform document. In plain language, it is a file that will look the same on the screen and in print, regardless of what kind of computer or printer someone is using and regardless of what software package was originally used to create it.

Although they contain the complete formatting of the original document, including fonts and images, PDF files are highly compressed, allowing complex information to be downloaded efficiently.

How to View PDF Files

Once the Acrobat Reader software is properly installed, you just need to click on a link to a .pdf file and it will be loaded for viewing on your computer.

How to Print PDF Files

When printing Adobe Acrobat PDF files from within your web browser, do not use the web browser print facility. Instead, use the print button at the left end of the special Adobe Acrobat application tool bar, which appears immediately above the viewing window.
