To save any publication, first select the 'PDF Download' for each title. A separate window will open, simply select the 'Save' button. The file will be saved to your local hard drive.
Important Note: If the file size is large, opening the file will take longer than usual or might even fail to open. This is, often, due to internet connection speed, and not because the link is not working. Saving large files to your local hard drive and opening them from your drive locally may reduce the problem.
