Ebook Central offers eBooks in two formats, depending on publisher preferences:

• EPUB is an HTML-based format that supports reflowable text. When users resize their browser or access the book on a smaller device like mobile devices or tablets, the text will automatically reflow to adjust to your screen size. Users can also adjust the font size for most eBooks in the Display Options menu within the EPUB Reader.
• PDF is an image-based format that keeps the look and feel of a printed book. The book has a set number of pages with a fixed width. These books may not display as well on smaller devices and may require additional zooming.

Though every effort has been made to support a fully accessible experience, there are some exceptions that are outside of our control:

• Some eBooks may not allow for text magnification or font-size increases
• Some eBooks may contain images that have not been given alt text
• Some eBooks may contain content that does not contain appropriate structure tags and headings
• Some eBooks may contain data tables that are not properly marked-up
• Some eBooks may include text in a different language than the primary language of the eBook

If the existing content does not meet the needs of users, remediation options are available and can be requested via the Support team. We continue to work with publishers to encourage them to provide content that meets current accessibility standards.
