The University of Rochester does permit outbound links to professional associations, state and government sites and regulatory bodies (e.g., JCAHO).
The University does NOT permit advertising on URMC sites by third parties (e.g., banner ads).
When a link is created to an external (non-URMC page), links should always open in a new window using target="_blank". When linking to another page within the URMC site, the target should remain in the same window. In the case of an external link, the user will be signaled that the link is opening a new window by using the link style, "link-external".
