Now you can easily convert your own selection of articles into a single PDF file!
Simply click in the box alongside any article in a list or above the title on any article page to add to your collection.
When you have completed your shopping, click the Convert to PDF button near the top of the right-hand column to produce the file. But be careful, if you have selected a lot, this may take some time!
Once the file has been produced you can view it online or save it to your computer; and there are even bookmarks in the file to help you find the beginning of each article.
