All Pennkeys have a status/affiliation assigned to them. Access to the library's e-resources is restricted to users with a valid PennKey and appropriate status/affiliation. The Penn Libraries cannot sponsor, create, or renew PennKeys. PennKeys can only be requested from individual departments. CHOP patrons may be referred to Biomedical Library staff at circbio@pobox.upenn.edu for further resolution of access issues. See any of the links below for further information.
