PDF copies are not being generated for articles created by the editors on the new website, but for longer articles that originate from journal issues prior to July 2014 the associated PDF has usually been retained on import from PJ Online.
The publisher's expectation is that most readers will find bookmarking online articles in the "My Library" area of the new interface more convenient than storing copies as files. (See explanation.)
To download an archive PDF, you should be logged in (or using a corporate subscription with IP access recognition).
To preserve a copy of a newer article or where no PDF is shown, either print the web page using the printer icon in the right-hand column or use locally installed PDF conversion software, such as Adobe Acrobat Pro, or a subscribed conversion service. You can also use your browser's "Save as" File menu option to save it to your local device as a web page, but you may find that such a file takes a long time to open. Please note that you may make only one copy of any article, and only for personal use (http://www.pharmaceutical-journal.com/services/permissions-and-reprints/), which means that such copies of Pharmaceutical Journal articles must not be stored on a shared server.
