Yes, and here is a guide to library services for alumni.  The good news, alumni have remote access to some databases  (not all) through Hopkins KnowledgeNet  Access to KnowledgeNet is complimentary for alumni.  Follow the link to find out the types of databases and how to sign in.

Also, alumni are welcome to visit the Eisenhower Library and its branches in DC, Columbia and Montgomery County and to use any of the resources on site. Here is a link to the Alumni Association page that explains these benefits and others.

Hope this helps!
