Advances in information technology have introduced both new capabilities and interesting challenges in accessing medical literature. More and more information resources exist in electronic format, such as online databases, journals, books, etc. instead of the traditional print format. In late 1998, there were thirty-five journal titles available online; in 2001, the number rose to over 4,000.1 Desk-top access to online resources is changing library use patterns, which challenges libraries to adjust to this transformed information access environment. Studies of the impact of the internet on information seeking behavior of users in medical environments could provide very valuable information for medical libraries seeking to adapt to this rapid and great evolution. This study aims to explore the impact of the Internet on information seeking behavior of medical students and faculty and their medical library use, to address the possible reasons for this change of information seeking behavior, and to identify the measures essential to the transition from traditional in-library use of resources to remote access. This study is conducted in two phases.
