Web Accessibility

Website Accessibility Introduction

The Pacific University Library website was designed and developed to follow the Web Content Accessibility Guidelines (WCAG) developed by the Web Accessibility Initiative (WIP) of The World Wide Web Consortium (W3C) the leading organization for setting international web standards and best practices.

The WCAG was built around the four main guiding principles of accessibility: perceivable, operable, understandable, and robust (also known by the POUR.) POUR is a process for approaching web accessibility by breaking it down into these four main components. Many technological challenges faced by people with disabilities fit under one or more of POUR principles.


In terms of accessibility, perceivable means the user’s ability to identify content and interface elements by means of their senses. For many users, this means perceiving a system primarily visually, while for others, perceivability may be a matter of sound and/or touch.


Is the user’s ability to successfully use controls, buttons, navigation, and other interactive elements. For some users, this includes the use of assistive technology like voice recognition, keyboards, screen readers etc.


Is the user’s ability to comprehend the content, learn, and remember how to use the Open Educational Resources (OER) on your website. Your OER should be consistent in its presentation and format, predictable in its design and usage patterns, and appropriate in its voice and tone to the audience.


The website’s content must be clear enough for it to be interpreted consistently by most website users, giving them the option to choose the technology they use to interact with websites, online documents, multimedia, and other information formats. Users should be allowed to choose their own technologies to access OER content.
