Log In via the Publisher
Some publisher websites let you sign in directly with your HarvardKey.
Find the sign in or log in option on the site, then look for language like:
- Institutional access
- Sign in through your institution
When prompted, search for Harvard Library and sign in with your HarvardKey. If both Harvard University and Harvard Library are listed, we suggest choosing Harvard Library.
