Accessibility of this platform
Keyboard-only navigation and visible focus
Most of the website can be navigated with a keyboard alone, but there is an exception to this is on the search results page where the “Sort by” dropdown menu is inaccessible via keyboard.
Throughout ProQuest History Vault, visible focus is given to a selected element by changes in the color, text styles and other visual changes. One exception to this is the search field menus on the Advanced Search page when navigating with a keyboard there is no visible focus.
Missing labels and alternative text
Throughout ProQuest History Vault, form elements and buttons are given accessible labels, so you can use assistive technologies to determine the purpose of various controls. The majority of elements have labels, but there are a small number of missing labels. In these cases, there are usually adjacent text labels that describe the purpose of the control. Exceptions to this are:
- Search input field
- Dropdown menus
- Checkboxes on the Advanced Search page
- Search button
- Help icon link
- Arrow icons that advance the user through lists in the product
In the above cases, while accessible labels are missing, there is descriptive text that appears before these controls that can help you understand their purpose.
All images that are purely decorative are either coded as background images or have null alternative text, so they do not interrupt the page when using a screen reader. However, we cannot guarantee that all images in the data have been given alternative text. Some full text documents are only in PDF image format making them unreadable to screen readers.
While most text throughout ProQuest History Vault meets minimum color contrast standards, there are cases where text does not have enough contrast with the background color:
- Dates on timeline events
- Headings in grey boxes
- White text on green buttons and header background
If color contrast is a concern for you, we recommend utilizing one of the free browser plugins that can increase text/background color contrast, such as the High Contrast extension
for Google Chrome.
Structure- links, titles and headings
Identification attribute values are unique on most active focusable elements. This allows assistive technologies to interpret and parse the content on the website. Exceptions to this in ProQuest History Vault are:
- Session link
- Navigation bar
- Sign-in link
Users can skip to the main content using a skip link, but the skip link is not visually displayed and only obvious to screen readers.
Pages in ProQuest History Vault are titled but are given generic titles that can make them difficult to distinguish if not looking at the menu navigation.
Headings are used throughout the website for visual consistency and information hierarchy although some headings are missing and heading levels are skipped in some cases.
The accessibility of ProQuest History Vault is a continual effort at ProQuest. Accessibility standards are built into our design, and style guides and included as part of requirements in our software development and quality assurance pipeline.
ProQuest History Vault code is checked for accessibility using a range of automated and manual checks including but not limited to:
- Color Contrast Analyzer provided by WebAIM
- Deque aXe accessibility testing tool
- High Contrast Chrome extension
- Keyboard-access manual testing and assessment
- WAVE (Web Accessibility Evaluation tool) provided by WebAIM
- JAWS with Windows
- VoiceOver with Mac
ProQuest History Vault is tested on the latest version Firefox, Safari, Chrome, and Edge, and on devices including Mac and Windows computers, and Android and iOS devices.
