This guides provides details about accessibility options at National University Library.

Browser Accessibility

Please note that some browsers work better than others with the Library website and its resources. If you experience an issue with a library resource, we recommend testing in a different browser.

Some accessibility features are common to all browsers, such as using the keyboard to zoom in or out on a web page:

Press CTRL + PLUS SIGN (+) to zoom in, or CTRL + HYPHEN (-) to zoom out.

Other options will vary from browser to browser. The most popular browsers seem to provide the most options and are further described in the box below. For a comprehensive comparison of browser accessibility options, please see the Wikipedia chart at

Internet Browsers

The Chrome browser supports assistive technology including some screen readers and magnifiers. It offers people with low vision several tools, including full-page zoom and high-contrast color. In addition, Chrome Extensions are extra features and functionality that you can easily add to your Chrome browser to customize it with functionality you need. There are many extensions which improve accessibility, or which help developers create accessible web applications, such as ChromeVox, ChromeShades, and ChromeVis.

Opera also supports fit to window and page zooming features.

Page Zoom
