Off-campus access to library licensed resources is protected by eRaider. However, no vendors directly recognize eRaider. For example, if you visit www.embase.com and attempt to login with your TTUHSC eRaider, it will fail.
The connecting point between library licensed resources and the eRaider system are the specially-crafted links on the library web pages. Always use the links on the library web pages to access library resources, and never create personal bookmarks to library resources in your web browser.
