Some resources on HealthLinks are governed by licensing agreements.
These agreements vary in their stringency, and limit how these
resources can be used. For more information on restrictions
that are monitored by the library, click on the

next to the resource. Lock icons are used to designate
resources with access restrictions that are monitored by the library.
Restrictions imposed and monitored by the publisher, such as individual
registration, are generally not noted.
See Connecting to UW Online Restricted Resources for information about using the UW Internet Connectivity Kit (UWICK) or the UW Libraries proxy server to access resources from off-campus.
