We are committed to ensuring that Black Literature Index is accessible to everyone. The accessibility of the site is under constant review and we are always looking for ways to improve the experience of the interface for all our visitors. If you have any questions or suggestions about the accessibility of this site, please submit those to us via the "Contact Us" link in the page footer.
A number of accessibility features have been implemented in Black Literature Index to make the site more accessible to as many people as possible. Some of these features may not be visible in your browser but can improve accessibility for people using assistive technologies.
You can use access keys as part of keystroke combinations (keyboard shortcuts) to navigate quickly to important features in this site without using a mouse. So that you don't have to learn a new set of keys each time, we have tried to ensure that the keys assigned are consistent with authoritative sources on the Web and other ProQuest products.
- 0 = Accessibility statement
- 1 = Home page
- 2 = Skip navigation
- 3 = Site map
- 4 = Search
- 6 = Help (opens in a new window)
To use access keys in Internet Explorer for Windows and FireFox 1.5:
- Hold down the ALT key and press the assigned access key.
- Press Enter (Internet Explorer only).
Mac users should hold down the Ctrl key and press the relevant access key.
Note: access keys may not be available to users of some screen reader software where they conflict with reserved keystroke combinations (e.g. Window Eyes).
Using The Tab Key
You can use the TAB key to navigate through the main features of the page such as links and form fields:
- Press the TAB key to move forward to the next feature
- or press SHIFT and the TAB key to move back to the previous feature.
All forms such as search forms and email forms have been implemented to make them easier to understand for people using assistive technology.
- Fields which are associated with each other have been grouped together within the HTML to demonstrate their relationship to one another.
- All fields have been given a label in the HTML to match the label for the field shown on the screen. These labels are not visible on the screen but will be read out by screen readers and other assistive technologies.
Headings and Links
Throughout the site every effort has been made to ensure that the information in a page is presented in a sensible order. Headings have been used to indicate the hierarchy of information and can also be used to navigate through a page. If you are using a screen reader try using the keystroke H to move forwards through the headings and SHIFT H to move backwards. Check your browser or screen reader instructions for full information on how to use headings as a navigation tool.
Links can be used to navigate through a page in a similar way. Check your browser or screen reader instructions for detailed information on how to navigate through the links on a page.
Navigation Aids and Warnings
A 'Skip over navigation' link has been provided at the top of each page to enable people using assistive technology or their keyboard to access Black Literature Index to go directly to the main content of the page without needing to repeat the navigation links. It is usually hidden from view but can be read by screen readers or displayed on the screen by using the TAB key or the correct Access Key.
The site map provides a list of links to all the main areas and sub-areas of the site. To open the Site Map click on the link displayed in the bottom navigation bar on every page, then follow the link for the page you wish to open.
Hidden text is used throughout Black Literature Index to provide additional assistance for people using screen readers.
For example: Error messages for forms are hidden at the top of the page so that when an error occurs the message is read out first.
Popup windows have been kept to a minimum. Whenever they occur, hidden text has been added to the link to warn people using screen readers that a new window will open and, where appropriate, the icon is displayed.
An alternative text description has been added to images, where appropriate, within <alt> and <title> tags in the html. The descriptions will be displayed as 'tooltips' in the browser when the mouse is hovered over the image or will be read out by screen readers. Images which have been used purely for decorative purposes contain a null value so they will not be read by screen readers or generate a 'tooltip' unnecessarily.
