Access to free PDFs is available in DiscoverE, the library's discovery tool. Use the search terms "Emory Digital Library" to find content.
Pull up the detailed record display, right click on the "PDF Version" link, and save the pdf to your computer. It can then be opened using Acrobat Reader outside of the web browser.
Note that there are still a few issues regarding browser-comptability with Adobe software. So it is best for users to save files to their own workstations, where they can open files with their own instance of Adobe Reader (or Preview in Mac OS).
