Barnes and Noble’s Nook eReaders can display PDFs, however the experience will probably only be optimal on the Nook Color. The other devices will be able to display the book, but it will probably be a relatively cumbersome experience. Because we felt that the layout, formatting and images were very important for the user experience, we recommend only using the guides on the Nook Color. If you have further questions, or run into problems installing the guides, feel free to contact us at firstname.lastname@example.org.
Installing on a Nook/Nook Color
The full instructions on using these kinds of files are here, but the key section for installing the guides is copying the files to your Nook:
You can connect your NOOK Color to a computer (using the NOOK Color microUSB cable) to transfer personal files. Your NOOK Color will appear on your computer as a removable drive. Just click on the file on your computer and copy it (drag-and-drop) to the appropriate NOOK Color folder.
Always Download to Your Computer First
This is very important. Even if you don’t plan on reading the e-Book on your home computer, you’ll want to download a version there for safe-keeping. The download link you will receive is good for 5 download attempts or 120 hours, whichever comes first, so you’ll want to make sure you have it somewhere safe where you can hold onto it. Save it to your computer hard drive so that you’ll know where it is the next time you want to access it.
