Voluntary Product Accessibility Template
In 2016, we completed an internal accessibility evaluation of the Credo Online Reference Service platform using the HTML CodeSniffer tool and several screenreader tools, and created Credo’s VPAT. Click here for Credo’s Voluntary Product Accessibility Template (VPAT) (PDF link). Please note that this applies only to the Credo Online Reference Service Platform.
Our InfoLit Courseware has also been evaluated for accessibility. Click here for the InfoLit Courseware's Voluntary Product Accessibility Template (VPAT) (PDF link).
The Credo Online Reference Service platform is "Compliant with Exceptions" to the Web Content Accessibility Guideline version 2.0. Click here for Credo's WCAG Statement of Conformance.
It is a priority for Credo that our system is accessible to all types of users, and we have designed Credo Online Reference Service to be used by people with disabilities.
Credo is committed to compliance with disability aids, such as screen readers. Specific elements have been put in place to aid visually-impaired users:
- Credo Online Reference Service has hyperlinks specifically placed to enable users with screen readers to skip common navigation elements of our pages and jump to a page's main content (visible only to Screenreader tools)
- We've created a narrative sitemap that describes pages within Credo Online Reference Service to users who cannot see them
- The Credo Online Reference Service platform provides text equivalents for images, charts and graphs.
Credo Online Reference Service has been designed to be used with either keyboard or mouse controls. Here's how to operate the various features of Credo Online Reference Service using only the keyboard.
Tab and Shift-Tab Keys
The tab (and shift-tab) keys allow you to move to each link or form element. As you press tab, the focus will move forward through the links. Shift-tab will move backwards. The last tab stop will cycle back to the first tab stop as you keep pressing tab. In a screenreader, the first link on any page will be a "Skip to Content" page.
Information overlays (such as book and entry summaries) that are normally shown when hovering the mouse over a book or entry link are also shown when the link receives focus via the tab key. When a link has focus, press enter to follow the link. Some links in Credo Online Reference Service are actions that are performed within the page being shown, for example links that expand or contract a hierarchical display of other links.
When focus is on a checkbox, press spacebar to toggle the check.
When focus is on a selection list, such as the subject selections offered on the search form, use the up or down arrow keys to change the selection.
When focus is on a radio button group, the left or right arrow keys will move the selected button.
The Mind Map is a graphical presentation of important terms related to a search term. The map contains a set of linked term "nodes." Each node is connected to other nodes that are related to that node. After doing a Mind Map search, the page will show a graphical user interface for manipulating the map. The Mind Map can be operated with the following key commands.
Use Tab to navigate through the node list. Enter selects a new node, which will re-draw the map. Navigating to the entry list on the right allows a user to select a reference entry related to the node at the center of the map.
