What is a PDF?

Portable Document Format (PDF) provides a richer environment than other text formats and also allows materials to be printed exactly as the author(s) intended, including much of the supplementary information such as; drawings, 3D, maps, full-colour graphics, photos, tables, charts etc.

The PDF file can be easily downloaded to your computer, enabling you to view it offline at your convenience. Documents published in PDF format are typically much larger than simple text files. If you are connected via a dial up connection or if your bandwidth is severely restricted you should consider the likely download time before attempting to retrieve such documents. In order to help you decide, we give the size of the PDF file alongside its description.

Letters to Journals, Research Articles and other editorial content are available to registered subscribers or institutional site license users as either Full Text (HTML) or as a PDF.
