Affordability and Accessibility
PDF is a familiar format for many. Here are some items to consider:
PDF (for print)
This format makes it easy for students to print out your book at minimal cost, and is useful for those without wifi at home, or for those who prefer to read extended texts in print. It is also useful for students who like to write in their books.
However, PDF is also a fairly inflexible format unless you have software that permits editing.
PDF (for digital distribution)
This is the standard PDF format, but blank pages are automatically omitted.
This is a fairly inflexible format unless you have software that permits editing. It is difficult to read on a mobile device. If the PDF is just a scanned image, screen readers will not work. The text must be readable (OCR’d) for screen readers to work properly.
