You can download a chapter, page range, or page as a PDF. These PDFs allow searching and selecting.
For downloading to an Android or iOS device, you need the free app Bluefire Reader. You will also need an Adobe ID.
Depending on GSU's access rights, some titles may say "not available for download."
This means that the book as a whole entity is unavailable for download. However, you can still download or print individual chapters. To do this you must be viewing the book. Then select the appropriate icon at the top of the reader.
