The Arizona Health Information Network (AZHIN) is a statewide member-driven organization committed to improving access to information for health sciences students and practitioners. Members include several hospitals and hospital systems, an academic health sciences center, and other diverse health care organizations. AZHIN offers its members unlimited Web access to ten well-known health sciences databases. This paper explores the impact that AZHIN has had on its member institutions. A survey asked members to reflect on AZHIN and its possible effects on the visibility of the librarian within the institution, relative dollars spent on AZHIN and range of resources available, Internet connectivity within their institution, access to AZHIN and other Internet resources, teaching, and benefits of collaboration. Results indicated that AZHIN members have access to a wider range of resources than they would otherwise. There are financial savings for some. Internet connectivity and AZHIN membership can provide the librarian with a broadened role and increased visibility. The availability of MEDLINE and other AZHIN resources encouraged some institutions to install Internet connectivity more quickly. Teaching library users has increased. Overall, AZHIN members recognized many benefits of their collaboration.
