Outlined below are some features of the main National Library website that have been implemented to ensure compliance with accessibility guidelines. Where possible these features will be added to older areas of the site which do not currently meet these guidelines.
Adobe Acrobat format (pdf)
- Some of the information on the website is available in PDF format to provide for easier reading and printing offline. This is accessible. Previous to version 5 of Adobe Acrobat there are less accessibility features. The National Library of Ireland have no control on what version the user might be viewing such PDF’s.
- Top level navigation is visible at all times.
- A breadcrumb link is available at the top of each page to assist in navigation.
- The home page and all internal pages include a search box and links to advanced search
Structured Semantic Mark-up
- The site uses structured semantic mark-up where possible. For example, internal content pages use H1 for all top level headings and list mark-up for internal navigation. real list mark-up is used for layout in order to restrict visual presentation coding to CSS declarations. This ensures that visual presentation specific mark-up does not clutter up the page and ensures that visual reading aids simply read each page on the site for what it is, e.g.: a list of information.
- Some links have title attributes which describe the link in greater detail (mouse rolls overs), unless the text of the link already fully describes the target (such as the headline of an article).
- Wherever possible, links are written to make sense out of context. Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on a page and allow the user to browse the list, separately from the page.
- Link text duplication is avoided; two links with the same link text always point to the same address.
- All content images used in the home page and elsewhere include descriptive ALT attributes.
- In addition to the use of cascading style sheets (CSS) to ensure the separation of visual layout and presentation, The National Library of Ireland site also makes use of style sheets to allow for flexible resizing of fonts to meet user requirements. If some users find that font sizes are too small they can small simply increase the default size used in their web browser software (for example, in Internet Explorer font sizes can be changed in the View Menu under 'Text Size').
