Header

Use the header to identify our websites and carry the main navigation.

When to use

Use the header if your website includes library.upenn.edu in the domain.

When to consider something else

Skip the header if your website is not part of Penn Libraries or if using it would be misleading. Some of our resources may appear on other websites without being part of our digital spaces.

How to use

Show the header on every page. Missing headers can confuse users.

List important website sections as links in the navigation. Use short, clear link labels. Avoid jargon or unfamiliar terms.

Present links in priority order. Put high-demand links on the left and low-demand links on the right.

Avoid org-structure navigation. Structure navigation around user tasks and information needs, not your internal organization.

Research your navigation. Test with users to build your information architecture and navigation structure. Keep testing to ensure updates meet user needs.

</div>

Add a service switcher

Place a service switcher in the service-switcher slot to help people move between Penn Libraries' main places to start.

<pennlibs-header service-name="Website Name">

  <a href="/section-a">Section A</a>
