Librarians: Your favourite icon or button
The button used for OpenURL links is important. This gives a visual clue for your users that the web page they are viewing contains link(s) to your OpenURL resolver.
The Router allows you to register a button image. This can be automatically included by service providers via the Router, in the same way that their OpenURLs automatically link to your resolver. You can also register "alt" text to be used with the image, to ensure that users of non-visual browsers are also given consistently recognisable links to your resolver.
Please note that though we strongly recommend to service providers that they use the button image and alt text that you provide, we are not in a position to enforce this.
