Accessibility features vary between e-book vendors. E-book platforms may have different built in accessibility features. They may allow you to create a high contrast mode/dark mode or change the background color, or the resource may be adapted for use with screen reading or read aloud software. Gale e-books, for example, have built in features that allow a user to change the font size, word spacing, and background color. They also have built in features that will translate the text or read it aloud for a reader.
AbilityNet is a website that provides step by step instructions on how to adapt a phone, computer, or tablet to meet a user's needs. Users can filter queries based on operating system and device. Users can also search for a specific need (e.g. making text larger) or filter the guides based on symptoms (e.g. hand pain) or condition (e.g. dyslexia).
