Manage Outside Tool

Outside Tool allows an institution to place a link on every PubMed record. This link points back to a resource offered by the institution for their users.

Contact Information

The contact information is used only by the LinkOut Team and is not publicly available. It is important to keep this information current because the library contact is the recipient of the “I forgot my password” automated email and to allow the LinkOut team to contact you in the event of a problem with your account.


Click Contact Info tab to see your current contact. Click Add/Edit to edit information.


On the next screen you can edit the current information or enter additional contacts by clicking Add Contact. When you are finished, click Save. Changes will take effect immediately.
