How do I access online journals?

Access is via HarvardKey and goes through a proxy server. Access is granted to: Employees of the SAO (Smithsonian Astrophysical Observatory) and HCO (Harvard College Observatory), Harvard Astronomy Department Graduate Students and other Center for Astrophysics (CfA) affiliates who have a current entry in the CfA Staff Database. Most frequently used journals are listed on our web page. Additional journal titles, frequently in full text, may be located via Harvard's HOLLIS catalogue.
