Sitewide Navigation Features

On the left hand side of every page in each Literature Collection there is a list of links to the main functional areas of the site. At the top of every page, exluding the homepage (help is on the left hand side there), there is a context-sensitive Help, which opens in a new window. There is also a link to the Site Map.

In addition, navigation options relevant to a particular page appear at the start of the content area, immediately following the main page heading e.g. Modify Search link on the Results page.

Chadwyck-Healey Literature Collections has been implemented with Section 508 of the U.S Federal Government Rehabilitation Act in mind. Read our VPAT statement - PDF for full details of how Chadwyck-Healey Literature Collections addresses the Section 508 accessibility standards for web-based information. The Voluntary Product Accessibility Template (VPAT) is a standard form developed by the Information Technology Industry Council and the General Services Administration to demonstrate how a product meets Section 508 requirements.

Colours used throughout the interface have been tested against the World Wide Web Consortium's (W3C) and Hewlett Packard's standards for luminosity contrast, color difference and brightness difference.

This Web site has been tested for total (monochromatic) colour vision deficiency and partial colour vision (Protanopia, Deuteranopia and Tritanopia).

Where appropriate, we have tried to ensure that the access keys assigned to this site are consistent with authoritative sources on the Web (e.g. “UK Government accesskeys standard” in Illustrated Handbook for Web Management Teams) and other ProQuest products.
