The volumes are presented in two formats: as webpages or as a PDF file (Portable Document Format) you can download. Please be aware that these PDFs are large and may take some time to download even on a Broadband Internet connection. If you are on a slow Internet connection such as a telephone dial-up you may not want to view the PDF files. Most computers are able to open and print PDF files. If you have any problem please vist the Adobe website where you download the free Adobe Reader software that opens PDF files
